This PR introduces disk cache for static pipelines. The pipelines are
stored in `<cache folder>/vk-pipeline-caches/static-shaders.bin`.
Due to limitations in some drivers we add a custom header to the
cache file to identify if the cache file was created by the same driver
for the same GPU for the same Blender.
Reading/writing the cache is skipped when running blender with
`--debug-gpu` as that would generate different shader modules. For
now that isn't a problem, but the final implementation would check
before compiling a shader if a certain key is in the pipeline cache if
that is the case the compilation step is skipped and the cached shader
module is used.

Base pipelines are used to optimize the vulkan pipeline creation.
Instead of building each pipeline from scratch a base pipeline can
be used to share resources and faster code-paths.
We used to overwrite the base pipeline with the last created pipeline.
This PR doesn't overwrite the base pipeline after it was initially set
giving less confusion when working with base pipelines.

This introduces the concept of an #AttributeFilter. It's used to tell a geometry
algorithm which attributes it should process/propagate and which can be ignored.
We already had something similar before named
`AnonymousAttributePropagationInfo`. However, as the name implies, this was
specific to anonymous attributes. This had some downsides:
* A lot of code had to be aware of the concept of anonymous attributes even if
it did nothing special with anonymous attributes.
* For non-anonymous attributes we often had a separate `Set<std::string> skip`
parameter. It's not nice to have to pass two kinds of filters around and to
have to construct a `Set<std::string>` in many cases.
`AttributeFilter` solves both of these downsides.
Technically, `AttributeFilter` could also just be a `FunctionRef<bool(StringRef
attribute_name)>`, but that also has some issues:
* The `bool` return value is often ambiguous, i.e. it's not clear if it means
that the attribute should be processed or not. Using an enum works better.
* Passing function refs around and combining them works, but can very easily
lead to dangling references.
* The default value of a `FunctionRef` is "empty", i.e. it can't be called. It's
generally more nice to not have a special case for the default value. Now the
default `AttributeFilter` propagates all attributes without any extra handling
on the call-site.

e420caab19 already fixed this for "manually" changing visibility, but
if this change comes through animation, these notifiers dont fire (rna
callbacks dont run).
So to resolve, also redraw on `ND_FRAME`, this is something every region
in animation editors listens to anyways, so probably right for
consistency (and to solve this bug), even though it might eat away some
ticks.

Move the functions
* `BKE_pose_apply_action_selected_bones`
* `BKE_pose_apply_action_all_bones`
* and `BKE_pose_apply_action_blend`
out of the blender kernel and into animrig.
This will allow solving #126969 without having to include
animrig code in the blender kernel.

Between 2.93 & 3.2 a regression was introduced where evaluated
meshes from the modifier stack would always have their deformed_only
value set to false.
Resolve by enabling for meshes returned by
BKE_mesh_wrapper_from_editmesh and ensure the value is kept when the
modifier duplicates the cage mesh.
Resolves#123138.
This shows the docking feedback very similar to how tooltips are shown
elsewhere. It describes the operation and also includes the icon and
name of the moving/changing area.

Decreases BVH build runtime by approximately 6%.
Improve cache locality in the initial splitting loop and the finalization
of mesh leaf nodes by processing them in separate loops. The second
loop calculates the node's vertex indices.
Speeds up building the sculpt BVH tree by over 3x.
The total bounds for all the triangles/grids in the current node is
recalculated for every iteration of the node splitting algorithm that
builds the BVH tree. The first step was parallelized, but since the
number of elements is just divided in half every time, many of the
subsequent bounds calculations are significantly large to benefit from
parallelism too (actually all of them for mesh BVH currently, since the
leaf size is about 4000).
Adds an option to the "Clear Recent Files List" operator to allow it
to remove only items that are not found. By default it clears "All
Items" but this can be changed to "Items Not Found".

For historical reasons, the BVH tree considered face sharpness similar
to material indices and tried to make the value match for all faces in a
node. This is unnecessary because PBVH drawing supports mixed
sharpness within a node.
For the draw face set brush, dynamic topology remesh, and "Show All",
push all the affected nodes in one call. This helps to decrease overhead
from multithreading and data access.
This works around an issue where eevee was rendering a pure black cube in certain shader configurations in the default scene (#122837). This only affects X Elite devices (8cx Gen3 is unaffected).

This commit rewrites the PBVH drawing using many of the principles from the
ongoing sculpt refactor. First of all, per BVH node overhead is minimized.
Previously the main entry point to the drawing API was per node, so there
was significant overhead fetching global data and maintaining caches on
a per-node basis. Now all of that "global" work happens for the entire
geometry.
We also now avoid creating wireframe index buffers and batches unless
the viewport actually requests wireframe data. This was theoretically
possible before, but the whole logic flow was so convoluted that the
optimization was too difficult. Similarly, multithreading is used more
consistently now. Because of OpenGL, flushing vertex/index buffers to
the GPU has to happen on the main thread, but everything else can be
multithreaded. With outer loops processing all relevant PBVH nodes,
it's now trivial to apply multithreading wherever possible.
Testing performance, overall this commit results in a 10% improvement in
the time between opening a file with a large mesh sculpt and the first
possible interaction. Specifically I measured a change from 8.4 to 7.6
seconds on a completely visible 16 million vertex mesh with a Ryzen 7950x.
I also measured a decrease in memory usage from 4.79 to 4.31 GB.
For multires I observed a similar improvement in memory usage,
though less of a performance improvement.
There are still significant opportunities for future improvement. #122775
would be particularly helpful. #99983 would be helpful too, though more
complicated, and #97665 describes the problems a bit more generally.

This allows more flexibility about how we store undo data. Potentially
we wouldn't need to store everything segmented per-node if we didn't
expose the `undo::Node` struct.

- Use `float3` C++ vector instead of pointers
- Return directly instead of using temporary boolean variable
- Use separate loops for "original positions" case to simplify hot loops
The issue is due to a dependency cycle which leads to access of data
which is not ready yet.
The dependency cycle was introduced in ada367a0e9.
This change makes it so there is no dependency cycle in the setup from
the report by re-routing dependencies a bit: the light linking now
bypasses the geometry component and is only wired to an operation
related on instancing collection (but not use by a boolean modifier).

Previously, the `AttributeIDRef` wrapper was needed because it also had to
contain a pointer to an `AnonymousAttributeID`. However, since
b279a6d703 this is not necessary anymore.
Therefore we can use "raw" `StringRef` now which reduces the mental overhead
when working with attributes and also simplifies code.

Functional Changes:
- Custom shapes using empties now supports line width.
- Line width is supported on MacOS.
- Fixed Stick bone drawing on MacOS.
Some shaders are duplicated and ported to the new
primitive expansion API.
The legacy code inside `overlay_armature.cc` have been
guarded behind `NO_LEGACY_OVERLAY` which can
be enabled to make sure no legacy code is used unnoticed.
This allows for spotting more easily code that needs to be
ported. Moreover, it is easier to remove this legacy code
when the time comes.

Resovle regression in [0].
Pointers in `action.chanbase` were used without first loading the
list-base. In this case the intention was to skip loading legacy
data, so clear the list instead.
