drm/i915/uapi: implement object placement extension
Add new extension to support setting an immutable-priority-list of
potential placements, at creation time.
If we use the normal gem_create or gem_create_ext without the
extensions/placements then we still get the old behaviour with only
placing the object in system memory.
v2(Daniel & Jason):
- Add a bunch of kernel-doc
- Simplify design for placements extension
Testcase: igt/gem_create/create-ext-placement-sanity-check
Testcase: igt/gem_create/create-ext-placement-each
Testcase: igt/gem_create/create-ext-placement-all
