Subject: [ovs-dev] [PATCH 22/40] datapath-windows: Add annotations for OvsReleaseEventQueueLock

Add function annotations for ` OvsReleaseEventQueueLock`.
We make it aware that it requires a certain dispatch level, that it
restores the dispatch level, that it requires a lock held and releases
a lock.
