feat(3p/nix/proto): Add additional worker-protocol operations

Browse source 
On the chopping block this time:

* requests/responses that return one or more store paths, and contain
  nothing else, have been changed to use the same types (StorePath and
  StorePaths, respectively)
* QuerySubstitutablePathInfos has been added. It should be noted that
  legacy Nix has two versions of this call, one that only queries a
  single info (deprecated) and one that queries multiple. We have only
  implemented the latter.
* QueryDerivationOutputs has been added.
