This adds two operators to the pose library context menu:

Replace Pose

Completely replaces the selected pose asset with a new one.
Unselected bones will effectively be removed from the asset. They are not be part of the new asset, just like they wouldn't be when you'd use Create Pose.
The pose asset is keyed on the current frame, regardless of where the original asset was keyed.
Asset data (description, copyright, tags, assigned catalog, etc.) are copied from the original pose asset.

Update Pose

Updates an existing pose asset to the new pose of selected bones.
Bones that were not part of the original pose asset are added to it.
Keys of unselected bones will remain as they are in the pose asset.
All keys are placed on the original keyframe.

For reference, the frame on which the pose asset is keyed influences which frame is used for rendering its preview image. This could influence choice in camera, backdrop color, etc. when those are animated in the scene.

The operators work in both the asset browser and the asset view (i.e. in the 3D viewport side-panel).

~~This patch requires blender/blender#108547 for the Replace Pose operator.~~ Since blender/blender#108547 has landed on main, there are no futher dependencies for this PR.

Limitations

This patch does not work around the limitation that Blender is only allowed to write to the currently-open blend file. As such, editing the pose library still requires you to open the blend file that contains the pose asset.

Future Work

Once this patch is in, people have used it a bit for actual work & the feature got polished, it might be a good idea to follow this up with "Update from Clipboard" and/or "Replace from Clipboard" operators. That could be used in conjunction with the "Copy Pose as Asset" operator.

9f89730744 Animation: pose library, add 'Replace Pose' operator

Add a 'Replace Pose' operator that completely replaces the selected
pose asset. It creates a new pose asset just like 'Create Pose', copies
the asset metadata from the selected asset to the newly created one, then
removes the selected asset.

This requires blender/blender#108547
