Stepping-specific media behavior shouldn't be tied to MTL as a platform, but rather specifically to the Xe_LPM+ IP. Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_MEDIA_STEP() is dropped in favor of IS_GT_IP_STEP, which checks the media IP version associated with a specific IP and also ensures that we're operating on the media GT, not the primary GT.
v2: - Switch to the IS_GT_IP_STEP macro.
