Make `ChainMonitor::monitors` private and expose monitor via getter

Exposing a `RwLock<HashMap<>>` directly was always a bit strange,
and in upcoming changes we'd like to change the internal
datastructure in `ChainMonitor`.

Further, the use of `RwLock` and `HashMap` meant we weren't able
to expose the ChannelMonitors themselves to users in bindings,
leaving a bindings/rust API gap.

Thus, we take this opportunity go expose ChannelMonitors directly
via a wrapper, hiding the internals of `ChainMonitor` behind
getters. We also update tests to use the new API.
