[PATCH i-g-t] lib/rendercopy_gen9: Use AUX_NONE for platforms with unified compression

[Zbigniew Kempczyński]

For non-MSAA surfaces when unified compression is configured in PAT
auxiliary surfaces must be set to AUX_NONE. I haven't noticed this
on Xe2+ before as it setting was silently ignored by hardware but
setting to AUX_CCS_E is incorrect and may fail on newer platforms.
