This patch implements the Keying Screen node for the Realtime
Compositor. Draw data was introduced to the Movie Clip ID to allow
caching of the keying screen.

This patch changes the interpolation algorithm utilized by the Keying
Screen node to a Gaussian Radial Basis Function Interpolation. This is
proposed because the current Voronoi triangulation based interpolation
has the following properties:
- Not temporally stable since the triangulation can abruptly change as
tracking markers change position.
- Not smooth in the mathematical sense, which is also readily visible in
the artists sense.
- Computationally expensive due to the triangulation and naive
rasterization algorithm.
On the other hand, the RBF interpolation method is temporally stable and
continuous, smooth and infinitely differentiable, and relatively simple
to compute assuming low number of markers, which is typically the case
for keying screen objects.
This breaks backward compatibility, but the keying screen is only used
as a secondary input for keying in typical compositor setups, so one
should expect minimal difference in outputs.

Improvements to `ui_but_menu_add_path_operators` so that it properly
differentiates between files and directories even if the filepath is
not slash terminated. It will also not add the operators to the menu
if the filepath does not exist.
---
Right-clicking on a pathname input we get a context menu that might contain "Open File Externally" and/or "Open Location Externally". But the first problem is that it does not check if this location exists, and we do have times where the paths do not exist yet. This PR makes this function a bool so that can return false if the files do not exist.
The second problem is that the function does not properly differentiate between a file path and directory path. For a directory path that is not slash terminated it will assume it is a file path. This PR actually checks the path (BLI_is_dir) to see if it really is a directory path.

Nodes recently gained the ability to group inputs into collapsible
panels. These were untranslated, so this commit:
- Adds the appropriate regex to extract node panels defined with
the `add_panel()` callback.
- Adds the `IFACE()` translation macro to the drawing code for the
nodes, as well as the properties.

Disambiguate:
- Rename "Near" to "Proximity" as a particle event type, because using
an adjective in this context is inconsistent and sounds
strange (even in English IMO).
Extract:
- "Skip" (Geometry nodes Simulation node output socket)
- "Bake" (Directory path to geometry nodes bake files in the modifier
UI)
- " (Recovered)" (File information in title bar)

This change restores the behavior of the flag to how it was prior to
the refactor which used ImBuf for storage in the RenderResult.
This flag still has issues with configurations when there are multiple
scenes in the .blend file, and that it is only "valid" when the image
is actually displayed. However, these limitations and quirks already
existed prior to the refactor commit.

This add a way to use a software clip plane in the
prepass shader (surf_depth_frag.glsl).
The benefit of using this instead of gl_ClipDistance
is that the rasterization pattern is given to match.
Which means that only the prepass shader have to use
this.
This is slow and should only be enabled when needed.
Previously, the geometry nodes modifier was converting the
viewer path to a compute context at the same time as it was
setting up side effect nodes for the geometry nodes evaluation.
Now, this is changed to be a two step process. First, the viewer
path is converted to the corresponding compute context.
Afterwards, a separate function sets side effect nodes up so
that the given node in the given compute context will be evaluated.
This has three main benefits:
* More obvious separation of concerns.
* Can reuse the code that maps a viewer path element to a compute
context already.
* With gizmo nodes (#112677), it may become necessary to add side
effect nodes based on a compute context, but without having a
corresponding viewer path.
The position validation when manipulating node group items now includes
outputs..inputs order in addition to sockets..panels order. The method
for finding a valid position has been simplified, it's just a single
iteration of insertion sort.
Versioning has been added to ensure files from 4.0 alpha with
potentially unsorted sockets get re-sorted. This uses `std::stable_sort`
so that sockets keep their relative order apart from the input/output
grouping.

If the DAE file was written with something other than Blender 4.0, it
doesn't have the bone collections info. That resulted in a nullptr, which
is now handled properly.
Overlay engine is currently responsible to initialize the framebuffers
depth_in_front texture. This is a hack and hasn't been ported to
Overlay-Next (yet). This PR skips copying the depth_in_front texture
when it isn't initialized yet.
Issue detected when working on Vulkan backend due its more
strictness.

It's possible for there to be no outputs under Wayland
(when unplugging monitors for e.g.) so this must be accounted for.
Also avoid calculating the window position when the GHOST backend
doesn't support window positions (which is the case for Wayland).
Add checks for the SDL backend too, where accessing the
screen & desktop size may fail.
The logic to handle word selection from double clicking ran even when
the event wasn't inside the button. This would pass an invalid position
to BLI_str_cursor_step_bounds_utf8 which hung.
Resolve by limiting word-selection to when the event is inside
the text editing field as well as clamping the position to ensure
it's within the allowed range.
