drm/xe/xe_migrate: Handle migration logic for xe2+ dgfx
During eviction (vram->sysmem), we use compressed -> uncompressed mapping.
During restore (sysmem->vram), we need to use mapping from
uncompressed -> uncompressed.
Handle logic for selecting the compressed identity map for eviction,
and selecting uncompressed map for restore operations.
v2: Move check of xe_migrate_ccs_emit() before calling
xe_migrate_ccs_copy(). (Nirmoy)
