3. fix(state): prevent watch channel deadlocks in the state (#3870)
* Revert "Drop the Chain watch channel lock before accessing the finalized state"

This reverts commit 8870944d13.

* Add a WatchReceiver wrapper that always clones the borrowed watch data

This avoids deadlocks, by holding the read lock for as short a time as possible.

* Drop the shared Arc<Chain>s as quickly as possible

This reduces memory usage.

* Make read::block more flexible, by accepting any AsRef<Chain>

* Make the block method docs consistent

* Avoid livelocks by explicitly dropping the borrow after the clone
