drm/xe/mtl: Add some initial MTL workarounds

This adds a handful of workarounds that apply to production steppings of
MTL:
 - Wa_14018575942
 - Wa_22016670082
 - Wa_14017856879
 - Wa_18019271663

Wa_22016670082 is currently only applied to the primary GT at the
moment, but may need to be extended to the media GT in the future if a
pending update to the workaround database gets finalized.

OOB workarounds will need to be implemented separately in future patches
for Wa_14016712196, Wa_16018063123, and Wa_18013179988.
