allocators: Add GstDmabufMeta

This meta can be added to the allocation query to indicate support
for dmabuf memory.  Optionally the drm_modifier can also be set in
the allocation query to indicate that the element supports some
certain set of drm modifiers (swizzling/tiling/compression/etc).
When the meta is attached to a buffer, the drm_modifier should
only be one which the src and sink both indicated support for in
the allocation query.
