[bt][host][fidl] Migrate to hanging-get style peer observation

- Introduced Host.WatchPeers which mimicks sys.Access.WatchPeers in its
signature and semantics.

- Removed the Host.ListPeers method and the  Host.OnDeviceUpdated and
Host.OnDeviceRemoved events in favor of Host.WatchPeers.

- Migrated all existing integration tests against bt-host to the new
API.

- Migrated existing expectations from control.RemoteDevice over to
sys.Peer.

- Migrated bt-gap to use the new API.
