This causes an assert with libepoxy, but was wrong already regardless. Refactor logic to work as follows: * GPU_exit() deletes backend resources * Destroy UI GPU resources with the context active * Call GPU_backend_exit() after deleting the context Ref D15291 Differential Revision: https://developer.blender.org/D15465
