Evan Shrubsole 1d2f30b8b9 Add utility WaitUntil for testing for an eventual condition
This replaces the WaitUntilCondition function that was used in the
peer_connection_encodings_integrationtest previously. Along with that it
adds tests and improved error message printing.

As a drive-by, matchers were added for RTCError as these are the return
type of this utility function.
