rename: add support for --at-rev, which marks as copy and removes the source

I had previously only added support for `--at-rev` to `hg cp`, but not
to `hg mv`. This patch adds that support. Just like for `hg cp`, it
marks the destination as copied from the source, and doesn't care if
the source file still exists (because it only supports the `-A` mode,
aka "don't touch files" mode). It works whether or not the source file
still exists. This matches the behavior of `hg mv -A` in the working
copy.

With rewrite.empty-successor=skip, b2 is skipped because it would become empty.

  $ hg rebase -s 2 -d 1 --config rewrite.empty-successor=skip --dry-run
  starting dry-run rebase; repository will not be changed
  rebasing 2:6e2aad5e0f3c "b2" (tip)
  note: not rebasing 2:6e2aad5e0f3c "b2" (tip), its destination already has all its changes
  dry-run rebase completed successfully; run without -n/--dry-run to perform this rebase

With rewrite.empty-successor=keep, b2 will be recreated although it became empty.

  $ hg rebase -s 2 -d 1 --config rewrite.empty-successor=keep
  rebasing 2:6e2aad5e0f3c "b2" (tip)
  note: created empty successor for 2:6e2aad5e0f3c "b2" (tip), its destination already has all its changes
