[Intel-xe] [PATCH v5 20/21] drm/xe/rtp: Also check gt type

[Lucas De Marchi]

When running rules on MTL and beyond that have media as a standalone GT,
the rule should only match if the gt passed as parameter match the
version/range/stepping that the rule is checking. This allows
workarounds affecting only the media GT to be applied only on that GT
and vice-versa.

For platforms before MTL, the GT will not be of media type, even if it
includes media engines. Make sure to cover that case by checking if the
platforma has standalone media.
