Fix T94387: Mesh sequence cache, crash when clicking a panel

The crash happens when opening a panel (added in rB43f5e761a66e87fed664a199cda867639f8daf3e)
when no CacheFile is set in the modifier.

To fix this, check that the CacheFile pointer is not null before attempting to draw anything.

Fixed bug when attempting to move Poly edges

Docs: Add to and cleanup attribute API docs

Most of the comment block is similar to the text in the source
code documentation wiki. It's helpful to have some text in
a header file too, so it's closer for programmers already looking
at the code.

This also uses more consistent syntax and wording in the comments
about the attribute API in `GeometryComponent`.

Cleanup: Use more common variable name

It's preferred to use `area` as a name for `ScrArea` variables.

Cleanup: Move customdata.c to C++

Breakdown Implementation

This patch adds the breakdown (or tween) functionality to the graph editor.

The factor defines the linear interpolation from left key to right key.

Shader Nodes: Convert bump node to use new socket builder

This node is a bit special in that it uses two internal sockets
for a hack for Eevee; see rBffd5e1e6acd296a187e7af016f9d7f8a9f209f87

As a result, the `SOCK_UNAVAIL` flag is exposed to socket builder API.

Blend To Neighbor Implementation

This patch adds the blend to neighbor operator to the Graph editor.

The operator acts like the blend to neighbor operator for a pose context, just working on keyframes.

Fix T94362: GPUMaterialTexture references freed ImageUser

The issue was caused by rB7e712b2d6a0d257d272ed35622b41d06274af8df
and the fact that `GPUMaterialTexture` contains an `ImageUser *` which
references the `ImageUser` on e.g. `NodeTexImage`.

Since the node tree update refactor, it is possible that the node tree changes
without changing the actual material. Therefore, either the renderer should
check if the node tree has changed or it should not store pointers to data in
node storage. The latter approach is implemented in this patch.
