drm/i915/dg2: Add Wa_16013000631
Invalidate IC cache through pipe control command as part of the ctx
restore flow through indirect ctx pointer.
v2:
- Move pipe control from xcs indirect context to the rcs indirect
context. We'll eventually need this on the CCS engines too, but
support for those hasn't landed yet.
