Merge JsepIceCandidate and IceCandidateInterface into IceCandidate

This consolidates the interface and implementation into a single
non-virtual, `final`, class named IceCandidate. For backwards
compatibility the types JsepIceCandidate and IceCandidateInterface are
declared as aliases for IceCandidate.

I'm not renaming files in this CL since that might break downstream
code. The merged implementation is for the most part in the same files
as before (split between the two jsep_ice_candidate.cc source files).

Along the way start migrating to `std::string ToString()` instead of the
current `bool ToString(std::string* out)` version.

No-Iwyu: grpc_signaling.cc has some unusual absl dependencies.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
