cast: clean up lint errors on commit

cast: cleanup rtp header and parsing

- Remove redundant rtp_header_parser which was mostly duplicated
  code that was modified for tests. Add all the necessary functionality
  to the existing rtp_parser and update tests to use rtp_parser

- remove rtp_receiver_defines.h and integrate it with rtp_defines.h where
  it makes more sense since it is not specific to receiver

- These changes help bring in adaptive playout data parsing into the tests
  which will help add unittests for adaptive playout for future CLs
