wined3d: Avoid waiting for a command buffer to finish executing to read off its queries.

Some games wait for query results on the frame executing the query,
expecting that enough time have passed for it to be available. By
requiring that the entire command buffer is done, we risk stalling the
whole frame if it wasn't flushed along the way. This patch drops this
requirement.

Mainly, we need to ensure that we don't call vkGetQueryPoolResults()
before the reset command is executed, and accidentally retrieve result
from previous usage. Using host query reset doesn't quite solve the
problem, as it might get called too early, if the application decides to
reuse a query without waiting for results. Besides, we want to support
devices where host query reset is not available.

To make it work, when a Vulkan query is no longer needed, we queue it
for resetting at command buffer submission time, and only mark it free
for reuse after this command buffer is finished executing.
