drm/i915: add in-kernel blitter client
The plan is to use the blitter engine for async object clearing when
using local memory, but before we can move the worker to get_pages() we
have to first tame some more of our struct_mutex usage. With this in
mind we should be able to upstream the object clearing as some
selftests, which should serve as a guinea pig for the ongoing locking
rework and upcoming async get_pages() framework.
