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