To relive us from the burden of previous obsolete workarounds, make a dedicated flush/invalidate callback for gen11. To fortify an independent single flush, do post sync op as there are indications that without it we don't flush everything. This should also make this callback more readily usable in tgl (see l3 fabric flush).
