Transform: don't inspect all scene objects in poll

From fix for T66311, c6a199e2542b4

Poll functions should never loop over entire scene,
in this case behave as other transform operators,
only checking the active screen.

Fix T66372 Convert to mesh with subdivision breaks topology

This was caused by a check that was not taking the restart index into
account.

Properly end VR sessions fixing crash on next session start

Previously, you had to restart Blender to start another session.

Fix T61808: remove confusing graying out of workspace that already exist

This was meant to help users see which users are likely useful to add, but
it's not so obvious and there are cases where it's useful to re-append the
same workspace.

Fix T65899, T66314, T61808: various issues appending workspaces

This fixes crashes, wrong names and inability to append workspaces in
edit mode. We now bypass the append operator so we can easily return
a datablock pointer and work in any mode.

Fix invalid state after calling append/link operator without any items

Fix missing update when setting rigid body world collection

Read custom alembic into CustomData and expose in RNA, cherry-pick from blender278
