drm/fourcc: define Intel Xe2 related tile4 ccs modifiers
Add Tile4 type ccs modifiers to indicate presence of compression on Xe2.
Here is defined I915_FORMAT_MOD_4_TILED_LNL_CCS which is meant for
integrated graphics with igpu related limitations
Here is also defined I915_FORMAT_MOD_4_TILED_BMG_CCS which is meant
for discrete graphics with dgpu related limitations
