Add a sctp_transport_interface build target

Introduce a dedicated sctp_transport_interface build target to improve
modularity and break an undesirable dependency. Previously,
`webrtc_sdp.cc` included `sctp_transport_internal.h` to access SCTP
constants.

The biggest code block in this CL is moving the block commented as
"Constants that are important to API users" block from the internal code
to `sctp_transport_interface.h`.

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
