Apply Wa_16018031267 / Wa_16018063123.  This necessitates submitting a
fastcolor blit as WABB and setting the copy engine arbitration to
round-robin mode.

v2:
- Rename old platform check in second patch to match
  declaration in first patch.
- Refactor second patch name to match first patch.

v3:
- Move NEEDS_FASTCOLOR_BLT_WABB to intel_gt.h.
- Refactor NEEDS_FASTCOLOR_BLT_WABB to make it more
  streamlined to use.
- Stop dividing PAGE_SIZE by sizeof(u32) when computing
  ctx_bb_ggtt_addr for lrc_setup_bb_per_ctx.
- Reduce comment complexity.
- Fix several checkpatch warnings.
