workspaces-view: Remove MosaicView

Browse Source 
The new layout does no longer support view switching, so merge
GenericWorkspacesView and SingleView, and remove MosaicView.
Also rename or remove workspace properties and functions which
are now unused.
The grid will have a comeback with the new DND behavior.
