This moves the implementation specific methods to separate classes (RtpSenderInternal/RtpReceiverInternal) so that the interface classes represent the interface that external applications can rely on. The reason this wasn't done earlier was that PeerConnection needed to store proxy pointers, but also needed to access implementation- specific methods on the underlying objects. This is now possible by using "RtpSenderProxyWithInternal<RtpSenderInternal>", which is a proxy that implements RtpSenderInterface but also provides direct access to an RtpSenderInternal.
