qpa: Make screen geometry updates (full and available geometry) atomic

Updating the geometry and available geometry in two steps means that
QScreen will be in an inconsistent state when emitting the geometry
change signal, as the available geometry has not been updated yet.

Piggy-backing changes to the availableGeometry based on the virtual
geometry changing does not make sense, so we now tie geometry and
availableGeometry (and their size variants) to their own separate
geometryChanged and availableGeometryChanged signals.
