Add globalRemove to QWaylandClientExtension

Adds support for handling of removal of the relevant global to
QtWaylandClientExtension. The user is responsible for destroying the object
once it becomes inactive to match the behavior on destruction.
Two signals for globals and their removal are added to QWaylandDisplay
to make it a bit nicer to use in a more "Qt-way". The addRregistryListener
function is kept for now until other places are ported.
