MINOR: quic: register QMux transport parameter as an extra frame

Use the newly introduced infrastructure for extra QUIC frames definition
for QMux usage. This only concerns the frame used for transport
parameters exchange.

This allows to remove specific code in qf_parser()/qf_builder() helper
functions.
