syncs: add Map.WithLock to allow mutations to the underlying map (#8101)
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.

Updates tailscale/corp#9115
