drm/i915: Add missing GSCCS documentation
Introduce the basic documentation about GSC CS.
This "GPU Basics" section is focused on explaining the hardware
rather than the driver/uapi, so let's make sure GSC is also

v2: Fixes from Matt: typos and acronym.
Fixes: 5fd974d164b4 ("drm/i915/mtl: add initial definitions for GSC CS")
