internal/genid: remove WhichFile

It seems safer to explicitly mention exactly which messages
have special handling, rather than special casing the .profile
that they live in. This is safer because there is no guarantee
that new messages won't be added to each of these files.

The protojson implementation is modified to no longer rely
on a isCustomType helper and instead return a marshal or unmarshal
function pointer that is non-nil if specialized serialization
exists for that message type.
