mvcc: avoid negative watcher count metrics (#11882) 
The watch count metrics are not robust to duplicate cancellations. These
cause the count to be decremented twice, leading eventually to negative
counts. We are seeing this in production. The duplicate cancellations
themselves are not themselves a big problem (except performance), but
they are caused by the new proactive cancellation logic (#11850) which
cancels proactively even immediately before initiating a Close, thus
nearly guaranteeing a Close-cancel race, as discussed in
watchable_store.go. We can avoid this in most cases by not sending a
cancellation when we are going to Close.

mvcc: no need to hold tx lock when converting kvs to watch events (#11701) 
Method `kvsToEvents` can take a long time if a large number of events need to be synchronized. However, this method does not access any shared resources, so it no need to hold the tx lock when executing. So we can move it outside to reduce lock holding time.
