drm/i915/mtl: add initial definitions for GSC CS

Browse Source 
Starting on MTL, the GSC is no longer managed with direct MMIO access,
but we instead have a dedicated command streamer for it. As a first step
for adding support for this CS, add the required definitions.
Note that, although it is now a CS, the GSC retains its old
class:instance value (OTHER_CLASS instance 6)
