Pass declared-but-yet-undefined DecoderDoctorDiagnostics pointer to various routines that contribute to deciding if a media format can be played, and those that create decoders. Points where a DecoderDoctorDiagnostics can be injected are currently marked with "/* DecoderDoctorDiagnostics* */ nullptr", and some will be used in following patches.
