syncs: add Map.WithLock to allow mutations to the underlying map
Some operations cannot be implemented with the prior API: * Iterating over the map and deleting keys * Iterating over the map and replacing items * Calling APIs that expect a native Go map Add a Map.WithLock method that acquires a write-lock on the map and then calls a user-provided closure with the underlying Go map. This allows users to interact with the Map as a regular Go map, but with the gaurantees that it is concurrent safe.
