xwayland: Try manual redirection for surface window in glamor_check_flip
requested to merge daenzer/xserver:xwl_glamor_check_flip-xwl_present_maybe_redirect_window-harder into master
If the surface window already uses automatic redirection, we can upgrade to manual redirection and save some blits with common use cases.
This fixes a minor performance regression from a65bb848 ('Revert "xwayland/glamor: Avoid implicit redirection with depth 32 parent windows"') with mutter >= 44.
