zink: rework query handling
this hooks up query objects to the batches that they're actively running on (and the related fence) in order to manage the lifetimes of queries more efficiently by calling vkCmdResetQueryPool only on init and when the query pool has been completely used up. additionally, this resolves some vk spec issues related to destroying pools with active queries note that any time a query pool is completely used up, results are lost, which is a very slight improvement on the previous abort() that was triggered in that scenario ref mesa/mesa#3000 Reviewed-by: Erik Faye-Lund <erik.faye-lund@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5533>
