Cleanup: Reduce indentation level

Exit early if the bevel width is zero instead of putting
the main function in an if statement.

Fix T79700: skin modifier: prevent error for vert-only mesh

Vert-only mesh is valid input for the skin modifier (displays isolated
cubes), prevent error message about missing root vertex in that case.

Fix T79676: Video Sequencer image sequence strip source path breaks when
saving with 'Remap Relative' option

Caused by rBf7386b97571e.

Logic in BKE_bpath_traverse_main calls the callback multiple times [as
often as there are images in the strip].

Prior to above commit, the callback was
'bpath_relative_convert_visit_cb' [this one did not have this problem -
since it returned early if the path was already made relative once]

After rBf7386b97571e though, the 'bpath_relative_rebase_visit_cb' is
used [this one should not be entered multiple times, it would modifiy the
directy again and again].

Luckily, we have a flag (BKE_BPATH_TRAVERSE_SKIP_MULTIFILE) that can be
used to prevent this (this will take care of only calling the callback
once in BKE_bpath_traverse_main for the VSE case)

Could be backported to 2.83 I think.

Cleanup: Reduce scope of variable declarations in bmesh_bevel.c

This commit generally moves variable declarations to the smallest scope
the variables are used in. This makes the code more readable by
making it clearer when variables are used and by removing the block
of variable declarations at the top of each function.

Sculpt: Option to not modify hidden Face Sets in Face Sets Edit

This options allows to perform Face Sets operations while preserving the
mesh visibility. Edit hidden face sets is enabled by default in order to
expand the visible area of the mesh with the grow/shrink operator, but
this can be changed in the keymap per edit operation as more operations
are supported.

Merge branch 'blender-v2.90-release' into master

Fix T79692: Full copy of scene makes Blender freeze if there is content directly in the master collection.

Old and new collections are the same data in Master collection case
here, so we cannot consider the `gobject` listbase of `collection_old`
as always immutable.

Added 3 new test cases for cloth, a check if no modiifer is added
