view: Refactor view destruction

Browse source 
Consolidates all of the view destruction code for xwl + xdg into one function.

Fixes several notable bugs along the way:
  - Fixes a crash when alt tabbing when a selected view gets destroyed.
  - Fixes the OSD not updating to reflect a view has been destroyed.
