Sculpt: Fix customdata_regen_active_refs

Fix crash when reading non standard Alembic velocity attribute type

Some software may export velocity as a different type than 3D vectors
(e.g. as colors or flat arrays or floats), so we need to explicitely
check for this.

A more robust attribute handling system allowing us to cope with other
software idiosyncrasies is on the way, so this fix will do for now.

Cleanup: missing verb in comment

Sculpt: fix problem with smooth brush defaults

Also wrapped some mv->flag OR's in a
macro, that can be switched with a macro
for debugging.

Cleanup: rename BKE_font.h -> BKE_vfont.h

Match API naming prefix (BKE_vfont_*) and DNA_vfont_types.h.

Cleanup: remove unused flag argument

Cleanup: move BLI_vfontdata.h to BKE_vfontdata.h

This didn't belong on blenlib since it uses DNA data types
and included a bad-level call to BKE_curve.h.

It also meant linking in blenlib would depend on the freetype library,
noticeable for thumbnail extraction (see D6408).

Sculpt: various fixes

* Fixed very nasty customdata bug where
if the first layer of a given type was
CD_TEMPORARY, then on being stripped out
of the customdata set the active references.

I think I tracked down where this happened, but
just to be safe I also wrote code to detect it and
regenerate the active refs too.

* Fixed rotate brush.
* Fixed mesh filter crashing with automasking on.

Cleanup: simplify ED_imbuf_sample_poll

Access the space data directly from the area.

Also remove redundant NULL check.

Cleanup: spelling in comments

Fix: Add missing function node declaration for RGB and Float Curve nodes

Sculpt: disable freelist mesh id backend,
trying to keep it disabled in builds
until I've tested it a bit more.

Add comment for last one-liner commit.

Sculpt: Fix transform sculpt tools

Sculpt: fix rotate brush

The branch finally compiles and opens the startup file

Merge branch 'master' into temp-vert-normals-cleanup

Cleanup: Remove unused DerivedMesh functions

The long term goal is completely removing DerivedMesh, and these
functions are making some refactoring of mesh normals (T91186) more
complicated. They are not used anywhere.

Cleanup: Clang tidy
