drm/i915/tgl: Gen-12 display can decompress surfaces compressed by the media engine

Browse source 
Detect the modifier corresponding to media compression to enable
display decompression for YUV and xRGB packed formats. A new modifier is
added so that the driver can distinguish between media and render
compressed buffers. Unlike render decompression, plane 6 and  plane 7 do not
support media decompression.

v2: Fix checkpatch warnings on code style (Lucas)

From DK:
Separate modifier array for planes that cannot decompress media (Ville)

v3: Support planar formats
v4: Switch plane order
v5:
- Use format block descriptors to get CCS subsampling calculation right
  everywhere.
- Extend the plane state normal view array to accommodate 4 color planes.
- Use helpers to convert between main and CCS planes.
v6: Add missing packed YUV formats to the MC format list. (Yang)
v7: Align UV planes to tile-row size.
