xwayland: refactor into xwl_window_post_damage() 

Refactor xwl_screen_post_damage() and split the window specific code
into a new function xwl_window_post_damage().

This is a pure refactoring, there are no behavioral changes. An assert
is added to xwl_window_post_damage() to ensure frame callbacks are not
leaked if a future patch changes the call.
