The redraw_pending boolean is used to schedule the first stage update after starting Clutter. This flag is superfluous because we have the pending_finish_queue_redraws flag which does the same. While at it, also remove the redraw_count debug variable, since there should be better ways to count the number of queued redraws nowadays, for example Sysprof marks. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1527
