[igt-dev] [PATCH i-g-t 87/89] lib/intel_bb: Remove intel_bb_assign_vm and tests

It's not used by anything other than the tests for that functionality
and it relies on setting the VM via SET_CONTEXT_PARAM which is
deprecated. Delete it for now. We can add it back in later if it's
actually useful and do it properly then.
