xwayland: Avoid repeatedly looping through window ancestor chain
Calling xwl_window_from_window means looping through the window ancestor
chain whenever it is called on a child window or on an automatically
redirected window.
Since these properties and the potential ancestor's xwl_window are constant
between window realization and unrealization, we can omit the looping by
always putting the respective xwl_window in the Window's private field on
its realization. If the Window doesn't feature an xwl_window on its own,
it's the xwl_window of its first ancestor with one.
