drm/xe/uapi: Add Tile ID information to the GT info query

As an information only. So Userspace can use this information
and be able to correlate different GTs.

Make API symmetric between Engine and GT info.

There's no need right now to include a tile_query entry
since there's no other information that we need from tile
that is not already exposed through different queries.

However, this could be added later if we have different Tile
information that could matter to userspace. But let's keep
the API ready for a direct reference to Tile ID based on
the GT entry.
