Vulkan: Don't wait QueueSerial if supportsHostQueryReset enabled In QueryVk::getResult() we are waiting for query's queueSerial to complete, even though QueryHelper::getUint64Result() we are also using VK_QUERY_RESULT_WAIT_BIT to ask vulkan driver to wait for result. Based on the comment, the reason for that queueSerial wait is because "its reset command may not have been performed by the GPU yet.". But if mFeatures.supportsHostQueryReset is enabled, we use vkResetQueryPoolEXT to reset the query, and this host reset is immediate, so there is no need to wait for queueSerial in this case. This CL disables the wait when host reset is enabled and relies on vkGetQueryPoolResults(VK_QUERY_RESULT_WAIT_BIT) to do actual wait. This should help performance on immediate renderer where the query result might be available before renderpass completion.
