DG2 and above supports flat-ccs what means object compression lays in
dedicated part of memory and is directly correlated with object location
in physical memory. As no mapping is possible from CPU side to this area
dedicated blitter command (XY_CTRL_SURF_COPY_BLT) was created to copy
from/to ccs data.
Test exercises scenarios:
1. block-copy without compression (TGL/DG1)
2. block-copy with flat-ccs compression (DG2+) + inplace decompression
3. ctrl-surf-copy which verifies copying ccs data to/from flat-ccs area
v2: set mip tail lod to 0xf to avoid overlap with lod
v3-v4: address review comments (Kamil) + setting uc_mocs (Ayaz)
