Turn RTCRtpContributingSource from an interface into a dictionary

Category: JavaScript
Type: New or changed feature
Status: Enabled by default (Chrome 73)
Intent stage: None

Summary

The specification requires RTCRtpContributingSource to be a dictionary, but it was previously shipped as an interface. With this change RTCRtpContributingSource will no longer have a prototype and getContributingSources() will create a new set of objects with each call.
