[Intel-xe] [PATCH v2 06/17] drm/xe/guc: Rename GEN11_SOFT_SCRATCH for clarity

That register is a completely different register, it's not the same as
SOFT_SCRATCH for GEN11 and beyond. Rename to to the same name as the
bspec uses, including the new variant for media. Also, move the
definitions to the guc header.
