Add a "configuration" channel to MCAP files for foxglove

This is helpful for doing certain types of analysis where you might want
to, e.g., correlate channel indices to a channel name/type (e.g., for
analyzing sent-too-fast errors or for using the ReplayTiming
message implemented by I471fefd96a4d043766b54dd4488726e24926a95f).
