This allows the entry point to be inlined at the caller site, paving the way for various optimizations. <msg>_encode now calls the non-inlined _<msg>_encode function in the .c file which does the preliminary work then calls __<msg>_encode to encode the actual type, if compound (or e.g. canardEncodeScalar).
Allows the processing of 0-length messages (which is true of some important ones in the DSDL) to be optimized away.

@tpwrules can you explain what the advantage is? Does this save flash space? |

Yes, it saves a bit, but it is also a prerequisite for table coding. |

Tested that ArduPilot master (bbd1d94d4) quadplane-can SITL frame still flies.
