This adds the ability to use all the math operations in the regular
utility "Math" node. The code is quite similar to the attribute vector
math node, with the simplification that the result is always a float.

This improves the fix introduced in rBdc8b31af578bfcf9f77dbce6d7b7da1006a3c8c1.
While it did not result in other bugs afaik, I thought it would be
good to make the fix more specific, in case some other code did
expect `layer->data` to be null. This updated fix checks for the
very specific case the fix was intended for.
This implements a new geometry node based on T84606.
It is the first node that generates a `VolumeComponent`.

The default one is now UVs are smoothed, boundaries are kept sharp.
After some time of experimentation seems this is better default from
interoperability point of view.

The issue was that boolean custom data layers were not written to files,
because the dna struct name `bool` does not exist. Adding a struct that
just contains a `bool/uint8_t` does not seem to be possible, it looks like
the minimum dna struct size is 4 bytes.
The proposed solution has two parts:
1. Write the custom data layer using `BLO_write_raw` instead of
`BLO_write_struct_array_by_name`.
2. When loading a file, reinitialize any custom data layer that was
not saved correctly (this is just a fix for existing files).

First step towards a better handling of relationships between IDs in
override context, especially when a resync is needed.
First, introduce a new flag to override operations,
`IDOVERRIDE_LIBRARY_FLAG_IDPOINTER_MATCH_REFERENCE`, for ID pointers.
It keeps track of whether an RNA ID pointer has been kept to its
'natural overriden ID' (in override hierarchy context), or has actually
been re-assigned to some other data-block.
Second, refactor how we deal with relationships between IDs in override
hierarchy code, especially in resync case. This will fixe several cases
listed in T83811, especially the case where an ID pointer to an existing
override needs to be updated to a new one due to a matching change in
linked data.
The `image_get_gpu_texture` didn't use the iuser->view_index but
recalculated the requested view again. This lead to inconsistent
behavior when switching between multi view textures or stereo textures.
This has been fixed by ensuring that the `iuser->view_index` is always
used.
An Image has only place to store 2 view textures. This is done for
right/left eye compositing. A multi view texture can have more views.
This would lead to reading and writing to unallocated space.
When a multiview texture is requested that is larger than 1. It will
always be cached as being the first eye. The `gpu_view` of the Image is
also used as a cache key to check this.
`bmain.relations` is used to store temp data of relations between IDs,
to speed-up some complex processes heavily relying on such information.
Previous implementation was failry unclear/confusing, and required a
not-so-nice hack to 'tag' some ID as processed.
New code changes as such:
* Using `from`/`to` naming (instead of `user`/`used`).
* More clear separation between `to` `id_pointer` and `from` one,
using an union instead of hacking around difference between `ID *` and
`ID **` pointers.
* Adds storage of `session_uuid` informations (mainly useful as
debug/ensuring proper consistency of data currently).
* Adds a structure per ID in the mapping. This enables possibility of
storing tags (and potentially more data in the future) per-ID,
without polluting the IDs themselves with very short-life info.

Currently this is needed to properly tag PointCache's for info update
(fixes an issue reported in T82503).
Suspect we may need this in more cases in the future though, RNA
assign/update processes are not always 100% enough to deal with
complicated corner cases.
We will need to expand this node soon to add weight/count for different
elements inside the collection. For that it is better to have the node
to use its own DNA.
Dividing the workload by number of tasks in float is imprecise and
lead in some cases to particles not being calculated at all
(example: 20000 particles, 144 tasks).
Switching this calculation to integer makes sure we don't lose count.

This node allows sampling a texture for every vertex based on some
mapping attribute. Typical attribute names are the name of a uv map
(e.g. "UVMap") and "position". However, every attribute that can be
converted to a vector implicitly is supported.
It should be noted that as of right now, uv map attributes can only be
accessed after a Point Distribute node.

The Asset Browser is still considered an experimental feature right now. But it
can be enabled by default for alpha builds, to get further testing and
feedback. It will hopefully be a non-experimental feature by the end of bcon1.
This is done in agreement with Dalai.
For the most part, this just adds boilerplate code for volume support in geometry nodes:
* Add `VolumeComponent` next to `MeshComponent`, etc.
* Support `VolumeComponent` in depsgraph object iterator.
Furthermore, I added initial volume support in a few nodes:
* The Object Info node outputs an object instance when the input is a volume object
(that will be the same for mesh objects soonish, to avoid copies).
* Support transforming a `VolumeComponent` in the Transform node.
* Support the `VolumeComponent` in Join Geometry nodes, but only when just one of the
inputs has a volume component for now.
Right now, there is no way to create a `VolumeComponent`, because the Object Info node
outputs an object instance. The `VolumeComponent` will be necessary for upcoming nodes,
which will generate volumes on the fly.
Viewport selection does not work correctly with `VolumeComponent`s currently. I don't
know why that is. That can be figured out a bit later, once we can actually create
new volumes in geometry nodes.

This commit moves runtime-only variables from the `SpaceNode`
DNA struct to a private struct in `node_intern.h`. Before, it was hard
to tell which data needed to be saved in files, this should make it
more clear.
Node that the `edittree` field is basically a runtime variable, since
it's set from the `treepath` list on read, but moving it would require
some more invasive changes that I don't think are worth it right now.
Also, not all of the moved variables were explicitly cleared on read--
`aspect` is set at the start of a redraw, `cursor` is set in a region
callback, and `recalc` was used as an update flag.

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.

By design the modified object transformations should still work and
affect the geometry nodes results. The current behaviour, however, would
make the geometry from the object info to not be affected by the
modified object transformations. This patch changes that by default.
In a similar fashion the Location, Rotation and Scale sockets outputs
should be aware of whether the output should be in the global space or in the
space of the nodetree.
To solve this, the patch introduces a new transformation space "enum"
where users can pick "Original" or "Relative" space.
Original
--------
Output the geometry relative to the input object transform, and the
location, rotation and scale relative to the world origin.
Relative
--------
Bring the input object geometry, location, rotation and scale into the
modified object maintaining the relative position between the two objects in
the scene.
Relative space violates a bit the design of the nodetree. The geometry in this
case is transformed so that moving the modified object doesn't interfere with
the geometry. This is particularly useful for the boolean node for instance.
"Original" is the default space, but old files are set to "Relative" for
backwards compatibility.

Copy the smooth setting when filling in curve caps.
For drawing this doesn't change behavior as a single normal is used
for all faces.
The difference may be noticed when converting to a mesh or with
modifiers applied.
Bevel caps always had incorrect normals, causing display glitches
in some cases.
It seems this never worked properly (at least 2.79 also had this bug).
Use the projection vector as the normal.
