Move ValidPathInfo serialization code to worker-protocol.{cc.hh}

Browse source 
It does not belong with the data type itself.

This also materializes the fact that `copyPath` does not do any version
negotiation just just hard-codes "16".

The non-standard interface of these serializers makes it harder to test,
but this is fixed in the next commit which then adds those tests.
