Use change signals on Window interface class.

QWaylandLayerSurface pulled data from the Window on startup. The Window
pushed data into the QWaylandLayerSurface on changes. Having two
patterns is a sign of something being off.

This moves everything to a single design, pulling from the public
interface. This allows us to drop a code path that meddles with
QWaylandWindow internals.
