drm/i915/selftests: exercise mmap migration
Exercise each of the migration scenarios, verifying that the final
placement and buffer contents match our expectations.
v2(Thomas): Replace for_i915_gem_ww() block with simpler object_lock()
v3:
- For testing purposes allow forcing the io_size such that we can
exercise the allocation + migration path on devices that don't have the
small BAR limit.
