Revert "xwayland: Redirect toplevel windows one by one"

This reverts commit 7889930ad9f0faa00e7a5d469a2b50beaf759c9f.

Redirecting the windows one by one this way doesn't handle unredirecting
windows that are reparented so they are no longer top-level windows.
This goes back to automatically redirecting all root sub-windows which
will handle reparenting correctly and we can hopefully find an
alternative fix for the shutdown crash.
