Yiwei Zhang 0a6dcd915e panvk/csf: rework cache flush reduction
Per Vulkan spec 7.9. Host Write Ordering Guarantees, queue submission
commands automatically perform a domain operation from host to device
for all writes performed before the command executes. That is to say,
host updates to the mappings can occur after the end of the command
recording and must be flushed implicitly at submission boundary.

Before this change, necessary cache flushes could be missed once the
app starts reusing pre-recorded command buffers. e.g. a simple buffer
copy cmd while the app only updates the source buffer mapping in
different submissions. This changes backs out most of the current
version of cache flush reduction while still assigning LATEST_FLUSH_ID
to at least the final batch itself. This aligns with panfrost_batch
submit behavior on the gallium side.

Test: dEQP-VK.synchronization*.timeline_semaphore.* pass w/o flakiness
      via venus-on-panvk

Fixes: 28e4d22497 ("panvk/csf: Pass a non-zero flush-id to benefit from cache flush reduction")
