commitctx: treat `filesadded` more like `filesremoved`

Accumulating the filename in a list will have a negligible cost and deal with
the list of added files like the other ones will make is code cleaning simpler.
The two variable with very close name is not great, but my plan is to split most
of the code in a separated function which will make the "problem" go away by
itself.

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
