drm/xe: Add GT_VER() to check version specific to gt type

In some situations we will need to check the version of the specific gt
being passed as argument, not if the device has a certain graphics/media
version.

This is extracted from a patch by Balasubramani Vivekanandan that
may need some rework, but this helper is still useful for other enabling
parts of Xe3p.
