Get real-time notification configuration from Chat Gateway 2 (#31492)

### Packages impacted by this PR
@azure/communication-signaling

### Describe the problem that is addressed by this PR
This PR is used for retrieving Trouter Config from Chat GW rather than
hardcode it in signaling client.
There are 2 main changes.
1.Remove the "environment" from SignalingClientOptions as it should be
retrieved from Chat GW;
2.Declare a TrouterConfigClientOptions and pass it to Signaling Client
constructor since this is needed for signaling client to make http call
to Chat Gateway.
