drm/xe: Set default MOCS value for cs instructions

CS instructions that dont have a explicit MOCS field will use this
default MOCS value.

To do this, it was necessary to initialize part of the mocs earlier
and add new function that loads another array of rtp entries set
during run-time.

This is still missing to handle of mocs read for platforms with
HAS_L3_CCS_READ(aka PVC).

v2:
- move to xe_hw_engine.c
- remove CMD_CCTL auxiliary macros

v3:
- rebased
