freedreno: Support offset query for multi-planar planes

This allows `gbm_bo_get_offset()` to return the correct offset for e.g.
the second plane of a resource with the NV12 format. Crucially this
fixes direct scanout / hardware plane usage in Mutter and possibly other
clients.

While on it also add support for stride, modifier and n_planes queries.
The later two should not change in behavior and just safe a few CPU
cycles. The stride query support in theory fixes queries for multi-plane
formats, however in practice most/all currently used formats such as NV12,
P010 and YUV420 use the same stride for all planes.
