drm/i915/uapi: expose GTT alignment
On some platforms we potentially have different alignment restrictions
depending on the memory type. We also now have different alignment
restrictions for the same region across different kernel versions.
Extend the region query to return the minimum required GTT alignment.
Testcase: igt@gem_create@create-ext-placement-alignment
Testcase: igt@i915_query@query-regions-sanity-check
