Previously, when a socket was detected to be unused, it was just grayed out.
This patch adds support for automatically hiding unused sockets based on this
convention: Menu inputs control visibility while other inputs only control
whether something is grayed out.
More specifically, an input is visible if any of these conditions is met:
* It affects the output currently.
* It never affects the output. In this case its usage does not depend on any
menu input.
* It is used if all non-menu inputs are considered to be unknown.
In the future, we could support customizing which inputs are allowed to control
visibility. For now it's good to use the convention that Blender generally
follows itself.
As before, panels are grayed out if they only contain grayed out sockets and
panels are hidden when they don't contain any visible sockets.
Hiding inputs works in group nodes, the Geometry Nodes modifier and node
operators. In theory it will work for all node tree types, but since only
Geometry Nodes supports the Menu Switch node currently, this patch currently
only makes a difference there.
The implementation reuses the existing `SocketUsageInferencer` with a different
sets of inputs. So no new core-inferencing logic was needed.
Design task: #132706.

The conversion from int to float is not supported natively
so it ends up happening beforehand on the CPU or as a
step before the vertex buffer can be used. It's better to just
upload floats in the first place.

This allows users to implement arbitrary camera models using OSL by writing
shaders that take an image position as input and compute ray origin and
direction.
The obvious applications for this are e.g. panorama modes, lens distortion
models and realistic lens simulation, but the possibilities are endless.
Currently, this is only supported on devices with OSL support, so CPU and
OptiX. However, it is independent from the shading model used, so custom
cameras can be used without getting the performance hit of OSL shading.
A few samples are provided as Text Editor templates.
One notable current limitation (in addition to the limited device support)
is that inverse mapping is not supported, so Window texture coordinates and
the Vector pass will not work with custom cameras.

pprop pointer created before initialization of op->customdata i.e.
`text_open_init()`. This triggers crash due to accessing member of
nullptr object `pprop->prop`

It's safer to pass a type so that it can be checked if delete should be
used instead. Also changes a few void pointer casts to const_cast so that
if the data becomes typed it's an error.

Remove long-deprecated constraints that will likely never be
implemented in this form.
- Rigid Body Joint Constraint was removed in 2.80, but some references
remained in the code. Versioning code was written that tried to
remove them on load, but since constraint initialization code sets
the type to CONSTRAINT_TYPE_NULL before versioning gets a chance,
the versioning code ended up never running. This has all been
removed.
- Python/Script Constraint never worked since 2.50 and showed an error
message in the UI panel.
These constraints now load as 'null' constraint, as seems to be
(looking at the code) the way that Blender currently deals with
removed constraint types. These still show up in the outliner and
python API, but have no UI panel. Removing such constraints completely
will be left for another time, as it is beyond the scope of removing
these two specific constraint types.

Use enum types for event modifier and types,
`wmEventModifierFlag` & `wmEventType` respectively.
This helps with readability and avoids unintended mixing with other
types. To quiet GCC's `-Wswitch` warnings many `default` cases needed
to be added to switch statements on event types.
Ref !136759
Callbacks: exec invoke & modal now use a typed enum wmOperatorStatus.
This helps avoid mistakes returning incompatible booleans or other
values which don't make sense for operators to return.
It also makes it more obvious functions in the WM API are intended
to be used to calculate return values for operator callbacks.
Operator enums have been moved into DNA_windowmanager_enums.h
so this can be used in other headers without loading other includes
indirectly.
No functional changes expected.

When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.

This caused build errors on the docs builder, I can't seem to reproduce
locally, so revert for now and have another look at some point in the
future.
Sadly as these changes usually go, this took 5c515e26bb and
2f0fc7fc9f with it as well.

This allows using C++ types in the region runtime data, which will
make it easier to move the remaining runtime data out of the
`ARegion` DNA type and improve code readability in these areas.

Without it sometimes it feels that search didn't work, when it just
happened that we were near the end of the file.
It is the default in popular external editors as well.
Ref: !127528
The resulting location was incorrect because the offset didn't account
for multi-byte characters and the logic had not been updated to use the
TXT_LINE_HEIGHT macro.
Also removes use of `goto` in favor of early return.
Ref !126720.
When an error occurs in the text editor the cursor moves to the
location of the error and selects the word there. However the text
space is only updated if the current cursor position moved, not if the
selection end did. So if the cursor is already at the end of the word,
it looks like nothing has changed while under the hood the word has
been selected.
This commit simply checks whether the selection has moved and updates
the space if so.

This was a consequence of the work done in #106321, where this specific
'active in UI' case was not identified and properly handled.
Now, consider most ID usages from UI (editors) as 'weak links', i.e.
keep a reference to these IDs even if they are only indirectly used.
Note that missing weak links will not create placeholders if the source
data is not found in the library anymore on load. they are just silently
dropped.

Small operator confirmations get separate confirm and cancel buttons,
better descriptions and configurable confirm button text. But still
popup at cursor location and can be cancelled with mouse movement.
