drm/xe: Add backpointer from gt to tile
Rather than a backpointer to the xe_device, a GT should have a
backpointer to its tile (which can then be used to lookup the device if
necessary).
The gt_to_xe() helper macro (which moves from xe_gt.h to xe_gt_types.h)
can and should still be used to jump directly from an xe_gt to
xe_device.
v2:
- Fix kunit test build
- Move a couple changes to the previous patch. (Lucas)
