Potential fix for T81963: Random crashes in liboverride code.

From the backtrace it looks like in some cases file save (which triggers
a general override updates) is done before other code has a chance to
re-generate pose data, leading to rna accessing freed memory.

I was never able to reproduce that here, so this is a tentative fix in
master, if it proves to be working for the studio it will be
cherry-picked into 2.91 release branch later.

Pose: Add a 'pose_ensure' new utils that only rebuilds if needed.

Avoids having to spread the check logic everywhere in the code.

Fix T81953: Python error in UV Editor Overlay popup

Leftover from rBe05ce1ea2029, 'use_image_editor_legacy_drawing' was
removed.

Geometry Nodes: initial support for evaluating geometry node groups

This is still very basic and does quite a few unnecessary computations.
Also the error handling is quite weak currently, so when invalid things are
connected, it will probably just crash.

Also the interface that individual nodes have to implement will have to change,
but the current solution is a good starting point.

Only the triangulate node is implemented for now.

Geometry Nodes: add an initial geometry class

Functions: add generic pointer class

This class represents a pointer whose type is only known at runtime.

Functions: add move operations to CPPType

Multires: Remove legacy subdivision code

Is no longer used, fully replaced with more powerful algorithm.

Multires: Cleanup, unused code

Multires: Remove legacy compatibility code

It was rather a huge chunk of code, which started to become
more harder to maintain with the transition to OpenSubdiv based
implementation. Because of this transition, the compatibility was
also rather on a poor side.

Remove compatibility support for pre-2.50.9 multires.

Compositor: Ensure keying node result is pre-multiplied

Historically the result of the keying node was violating alpha
pre-multiplication rules in Blender: it was simply overriding
the alpha channel of input.

This change makes it so keying node mixes alpha into the input,
which solves the following issues:

- The result is properly pre-multiplied, no need in separate
alpha-convert node anymore.

- Allows to more easily stack keying nodes.
This usecase was never really investigated, but since previously
alpha is always overwritten it was never possible to easily stack
nodes. Now it is at something to be tried.

Unfortunately, this breaks compatibility with existing files, where
alpha-convert node is to be manually removed.

From implementation side this is done as a dedicated operation since
there was no ready-to-use operation. Maybe in the future it might
be replaced with some sort of vector math node.
