Fix incorrect Face Sets when using mask extract

Mask extract modifies the topology when adding the boundary loop, so
previous face sets may not be correct in the new mesh. Remove the face
sets datalayer and let sculpt mode rebuild it when entering sculpt mode
in the new object.

Fix build error with WITH_XR_OPENXR disabled

Fix visual artifacts with partially hidden meshes and mask extract

The previous behaivour didn't make sense as sculpt mode was still active
when switching to the new object, so it was rendering inconrrectly.

Update viewport rotation origin when changing Face Set visibility

Small UX fix. When hidding everything but the active face set with H,
the last stroke lotation center can be in a part of the model that is
hidden, so viewport navigation becomes confusing until you start a new
stroke on the visible face set. Now the viewport navigation rotation
center is updated to the active vertex when using a visibility operation
that uses it, so it always rotates using the visible face set as the
origin.

Fix T61234 Mirroring Grease Pencil keyframes in the Dopesheet fails

`ANIM_animdata_update()` did not sort grease pencil frames. A
pre-existing comment stated this wouldn't be necessary as
`posttrans_gpd_clean()` already does this. However, this is only
applicable when the change is performed via the transform system. The
mirror operator doesn't call `posttrans_gpd_clean()`, invalidating the
assumption in the comment.

I moved the sorting code into `BKE_gpencil_layer_frames_sort()`, which
is now called from both `ANIM_animdata_update()` and
`posttrans_gpd_clean()`.

UI: Add 7 new community themes

This commit adds 7 themes submitted by the community on Devtalk. These themes both serve specific purposes, provide a greater variety in look & feel, and serve as welcoming homes for users coming on board from other packages. This is the initial commit, but these themes can be continuously updated over time to fix issues and keep them up to date with changes.

Thanks to all contributors, and in particular the makes of the picked themes: Pierre Schiller, Edward Agwi, Vojt?ch Lacina, Michail Soluyanov, Jason van Gumster, Mr Wax Police & Jonathan Lampel.
