* Add SubdAttributeInterpolation class for linear attribute interpolation.
* Dicing computes ptex UV and face ID for interpolation.
* Simplify mesh storage of subd primitive counts
* Remove kernel code for subd attribute interpolation
* Remove patch table packing and upload
The old optimization adds a fair amount of complexity to the kernel, affecting
performance even when not using the feature. It's also not that useful as it
does not work for UVs that needs special interpolation. With this simpler code
it should be easier to make it feature complete.

There is a bug in OpenEXR bug where it requests at least 4096 bytes even
if the file is smaller than that. Work around it by padding with zeros.
This was fixed upstream in commit 97f857131e6b4c43ab after the 3.3.2
release, but not in any official release yet.

This replaces the implicit use of the `radius` attribute on the input
curves with an input field `Scale` that gets evaluated on the point
domain of the input curves to scale the profile.
It wasn't super intuitive that the `radius` would actually act as
a scale of the profile. E.g. if the radius of the input curve was
`1 meter` the resulting profile was unscaled (scaled by 1), but
wouldn't necessarily have a size of `1 meter` (only if the profile
also had a size of 1m)! If imperial units were used, `3.28084 ft`
would correspond to a scale of 1.
This change makes this behavior a lot more clear and potentially
removes the need for the assumption that the default curve radius
is `1.0f` (Ideally, the default curve radius should be `0.01f`).
While we did consider making the `Scale` input use the `radius`
field implicitly by default, we decided against it, because it again
"hides" the dependency on the radius and the fact that the radius
is used as a scale. Letting the user make this decision seems better.

The issue was that the `FCURVE_DISABLED` flag is set when an
RNA path cannot be resolved, and that skips evaluation.
However in the specific case, that is actually something expected as
the property only exists on one ID and not the other.

Part of #134755 / #134766.
Add the blend file name and directory path to the tooltip of assets in
custom asset libraries (as configured in the Preferences), for the asset
browser and asset shelf. This information is often important when
dealing with production assets. In the asset shelf it wasn't available
at all.
Based on feedback from the Blender Studio.
Using `UI_but_func_tooltip_custom_set()` to create a custom tooltip
would completely disable the quicker label tooltip, even when explicitly
set using `UI_but_func_tooltip_label_set()`. Instead the quick label
should show first, and then the full tooltip once the usual tooltip
timer is reached.
**How to reproduce:**
1. Add Cryptomatte Node
2. Enable 'Object' render passes
3. Connect Cryptomatte to output (composite or viewer node)
4. Optional: set matte ID
5. (Do not connect input image)
6. Render
7. Observe invalid output image (or assert in debug build)
(see also PR for an example blend file)
Only CPU is affected. The solution follows the behavior of the GPU backend, where the input color of the single value input image is multiplied with the matte result to produce a non constant output.

Add an explanation to the keyframe insertion function
`animrig::insert_keyframes()` as to why it does not use
`ID_RECALC_ANIMATION`:
Animation flushing would be quite annoying in the following case:
- Key Cube's loc/rot/scale.
- Go to another frame.
- Translate, rotate, and scale the cube.
- Hover over the loc/rot/scale properties and one by one press 'I' to
insert a key there.
If `ID_RECALC_ANIMATION` were used, keying the location would immediately
cause a flush of the animation data, popping the rotation and scale back
to their animated values.
No functional changes.

When saving a file, move the catalog service from the runtime asset library into the new on-disk
asset library. This makes all catalog data like the undo history and deleted catalogs be preserved.
The fact that a new asset library type gets allocated is an implementation detail that shouldn't
affect behavior.
Once the service is moved, an undo push is added (so this state can be restored to), and if the new
.blend file location can be associated with a catalog definition file, its catalogs are merged in.
Includes unit tests.

This removes the use of `system_gpu_context_mutex`
which was making render command submission threadsafe.
The only issue is the concurent usage of GPUShader objects.
To fix this, we only guard the submission section which
are the only parts that uses the GPUShaders.
Removing this critical section all together requires some changes
in the GPUShader. See #135406
Rel #134690

Material user count in duplicated ob.data is not updated. Separate layer
operation later iterates over all the material slots thenremoves unused
slots from respective objects. Since id.us=1 for individual material, if
material is used by one object but not the other, count is decremented
to zero. If we use `USER_DUP_GPENCIL` then user count is properly
handled in `grease_pencil_foreach_id/id_copy_libmanagement_cb`.

When a layer channel is clicked to select inside dopesheet editor, this
sets the flag `GP_LAYER_TREE_NODE_SELECT` (i.e. is_selected() to true),
It prevents separate layer operation to create a new object for this
layer.

This PR enabled GPU based subdivision on Metal.
Most work is done in #135296.
- Metal max storage bindings for compute shaders were never set.
Some performance figures: Suzanne 6 subdivision levels
| Machine | CPU Subdivision | GPU Subdivision |
| --------------- | --------------- | --------------- |
| M1 Studio Ultra | 7fps | 12 fps |
| M2 Air | 3fps | 11 fps |

This PR enabled GPU subdivision on Vulkan backend. Measured
performance is slower compared to CPU on my system. But it is
expected that other bottlenecks should be solved in order to
fully benefit from this feature.
We enable it so we keep track of the performance bottlenecks.

Adjust the "Remove Empty Animation Data" operator so that it properly
handles slotted Actions. It was still investigating the legacy F-Curve
list, and thus always considered Actions as "empty".

Add a new RNA function `ActionSlot.users()` that returns the
data-blocks that are animated by this slot.
This covers direct assignment of the action & slot, but also use in
the NLA and in Action constraints.
```python
>>> D.actions['SuzanneAction'].slots['OBSuzanne'].users()
[bpy.data.objects['Suzanne']]
```
This was implemented as a function, and not a collection property,
because Blender's bookkeeping of the slot users can be marked 'dirty'.
In that case the slot user list needs to be rebuilt, which happens for
all Actions and all their slots simultaneously. This was considered
too broad a data-changing action to 'hide' inside a getter of a
property. Also it needs a `bmain` pointer, which is not available in
getters, but is available in functions.

draw_attribute_warnings() called in every attribute panel code.
Following function iterates through entire attribute list
mesh.attributes along with vgroup list to identify the colliding name.
This results in printing collision names in irrelavant panels. Now fixed
by passing relevant attributes to compare in `draw_attribute_warnings`.
First find colliding names, add them to the list if they exists in current attribute list
passed to the function

`GPU_vertbuf_update_sub` is used by GPU based subdivision to integrate
quads, triangles and edges. This is just an implementation to make it
