panvk/csf: Pass a non-zero flush-id to benefit from cache flush reduction

Boris Brezillon requested to merge bbrezillon/mesa:panvk-csf-cache-flush-eliminination into main

What does this MR do and why?

The cache flush reduction mechanism relies on the flush ID to conditionally eliminate cache flush requests if another cache flush happened between the time the flush ID was retrieved and the time the flush operation happens.

Store the current flush ID at EndCommandBuffer() time, and pass it back to the submit ioctl().
