xwayland: handle override_redirect flag changes

The override_redirect flag can change on configure notify and
on map notify. This adds an event to know when it changes.

This removes wlr_xwayland_surface_is_unmanaged which was wrongly
using the window type to decide whether the view should be
unmanaged.

A similar patch was proposed to Weston, but has never been
merged upstream [1].
