This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

Ref D14069
Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

The strings in the `get_description` functions for operators need
translation, they are not found by the translation system automatically,
and there is no translation applied afterwards either (as far as I could
tell). Some used `N_` before, but most did nothing.

Point cloud is two separate words, this just changes comments in
a few places where we were inconsistent. A small wording change
to another comment is also included.
This adds a toggle to node group inputs exposed in the modifier to use
an attribute instead of a single value. When the toggle is pressed, the
button switches to a text button to choose an attribute name. Attribute
search isn't implemented here yet.
One confusing thing is that some values can't be driven by attributes
at all, like the size of a primitive node. In that case, we should have
a node warning, but that will be separate since it's more general.
We can also have an option to turn off this toggle in node group
input settings.
The two new properties for each input are stored with the same name
as the value, but with `"_use_attribute"` and `"_attribute_name"``
suffixes. The properties are not added for socket types that don't
support attribute input, like object sockets.

Before this patch attempting to remove a particle modifier programmatically
through Python would fail, because it deleted the modifier associated with
the currently active particle system instead of the one passed as an argument
to `bpy.types.ObjectModifiers.remove()`.
This fix adds an additional argument for the particle system to
`object_remove_particle_system`. This allows to specify which particle system
and its associated modifier shall be removed. In case of
`particle_system_remove_exec` it will remain the currently active particle
system, whereas `object_remove_particle_system` passes the particle system
of the modifier. Hence, the correct modifier will be removed.

`BKE_displist_make_curveTypes` had a `for_orco` argument that was

None of these generic poll functions had NULL pointer checks,
since all operators that use these functions expect a valid constraint,
modifier .. etc. Add the NULL check to the poll function.

The trouble was that there was a context pointer "modifier" in the
property editor context that returned the active modifier. But the
"modifier" variable was already used in many places, for pointers
that are *not* equivalent to the active modifier.
The context pointer for the active modifier was unecessary anyway.
If we need to access a context pointer for the active modifier in the
property editor then we can add it. Until then it only adds confusion.
Earlier last year, the shortcuts on hover were built as a way to regain
speed lost by removing the "Apply" and "Copy" buttons from the panel.
For the active modifier concept introduced for geometry nodes, the
shortcuts were changed to only affect the active modifier.
Based on feedback, this change slowed down many people's interaction
with the modifier stack so the UI team decided to return hover shortcuts
for modifier panels.
The downside of this change is that it looks like the active modifier is
"selected" and it could be confusing that the modifier shortcuts don't
apply to it. We can explore different ways to display the active status
to address this.
Ref T87012
Since "Applied Modifier" was always added last, it obscured more important
messages when using the shortcut to delete modifiers. The purpose of the
report when using the shortcut was to make it clear that something
happened. Since another report does that anyway, only display the
"Applied Modifier" report if the report list length hasn't changed.
Things like pointers to particle systems, or softbody data being stored
outside of its modifier, make it impossible for internal modifier copy
data code to be self-contained currently. It requires extra processing.
In existing code this was handled in several different places, in
several ways, and alltogether fairly inconsistently. Some cases were
even not properly handled, causing e.g. crashes as in T82945.
This commit addresses those issues by:
* Adding comments about the hackish/unsafe parts `psys` implies when
copying some modifier data (since we need to ensure particle system
copying and remapping of those pointers separately).
* Adding as-best-as-possible handling of those cases to
`BKE_object_copy_modifier` (note that it remains fragile, but is
expected to behave 'good enough' in any practical usecase).
* Remove special handling for specific editor code
(`copy_or_reuse_particle_system`). This should never have been
accepted in ED code area, and is now handled by
`BKE_object_copy_modifier`.
* Factorize copying of the whole modifier stack into new
`BKE_object_modifier_stack_copy`, now used by both `object_copy_data`
and `BKE_object_link_modifiers`.
Note that this implies that `BKE_object_copy_modifier` and
`BKE_object_copy_gpencil_modifier` are now to be used exclusively to
copy single modifiers. Full modifier stack copy should always use
`BKE_object_modifier_stack_copy` instead.
Fix T82945: Crash when dragging modifiers in Outliner.

These two operators (one for grease pencil, one for other objects)
copy a single modifier from the active object to all selected objects.
The operators are exposed in the dropdown menus in modifier headers.
Note that It's currently possible to drag and drop modifiers between
objects in the outliner, but that only works for dragging to one object
at a time. Modifiers can also be copied with the "Make Links" operator,
but that copies *all* modifiers rather than just one. The placement
and scope of these new operators allow for more useful poll messages
and error messages as well.
Every object type that supports modifiers is supported. Although hook
and collision modifiers aren't supported because of an unexplained
comment in `BKE_object_copy_modifier`, other than that, every modifier
type is supported, including particle systems, nodes modifiers, etc.
The new modifiers are set active, which required two small tweaks to
`object.c` and `particle.c`.

It's easier to read and less 'weird' to check that an item is non-local
in a liboverride data-block, than the other way around. Thanks to
@sybren for noticing it.
RNA collections that support insertion of new items in liboverride
data-block need a special way to distiguish between locale and
orig-from-linked items (since some operations are allowed on the forer,
but no the latter).
In future we want a proper solution to abstract that at the
`BKE_lib_override` level, but for now we need to add some code for each
case.
Note that this commit also fixes a few potential issues with GPencil
modifiers, and constraints, regarding their handling of local overrides.
This commit adds functions to set and get the object's active
modifier, which is stored as a flag in the ModifierData struct,
similar to constraints. This will be used to set the context in
the node editor. There are no visible changes in this commit.
Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active
object and its active modifier. To keep the node group from changing,
just pin the node group in the header.
* Shortcuts performed while there is an active modifier will affect
only that modifier (the exception is the A to expand the modifiers).
* Clicking anywhere on the empty space in a modifier's panel will make it active.
These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators.
Second is a change to removing modifiers, where there is now a separate
function to remove a modifier from an object's list, in order to handle
changing the active.
Finally, the panel handler needs a small tweak so that this "click in panel"
event can be handled afterwards.
This is the initial merge from the geometry-nodes branch.

Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.
It includes commits from:
* Dalai Felinto
* Hans Goudey
* Jacques Lucke
* Léo Depoix

`WM_operator_properties_filesel()` allows C operators to set a display or sort
type for the File Browser to use. But the File Browser would always override
that because of an invalid `_is_set()` check. (The operators don't actually set
the value, they only set the property's default value.)
The only operator affected by this is "Recover Auto Save". It is supposed to
show a vertical list ordered chronologically. It used settings from the
previous File Browser usage before this patch.
Operators using the File Browser should generally use
`FILE_DEFAULTDISPLAY`/`FILE_SORT_DEFAULT` now, except if they have a reason not
to. See comments at their definition.
----
This makes it so operators that set a different display or sort type
don't change the sort or display type for the next File Browser operation.
So using "Recover Auto Save" entirely isolates display and sort type from other
operations.
