Added a new `register_event_sink` method that registers event sinks using the new `EventSinkSpecification` struct. This is general enough that we can use it to implement the older registration methods. This is a breaking change, but Desktop is the only platform that's will be affected. We can resolve the breakage when we do the next vendor.

I kept these around since it was simple enough to continue to support them, but maybe we should remove them and encourage everyone to use the new API.

This is the main reason for this change. On Desktop, when I went to wire up the error-reporting code, I had issues because both the event's target matched and the min-level matched, so we were getting duplicate events and would be reporting each error twice.
