drm/xe/gsc: Track the platform in the compatibility version

The GSC compatibility version number is reset for each new platform. To
indicate this, the version includes a number that identifies the
platform (102 = MTL, 104 = LNL); this matches what happens for the
release version, where the major number also identifies a platform.

To make it clearer in our logs that the compatibility version is
specific to the platform, it is useful to include this platform number.
However, given that our binary names already include the platform, it is
not necessary to add this extra number there.
