fix(tvix/store/pathinfo): use gRPC NarCalculationService r/8833

If the PathInfoService is using gRPC, expose it via the
nar_calculation_service() method in the PathInfoService.

Also pass nar_calculation_service through in tha blanket impl.

This now causes a `tvix-store import` using the default config to not
fall back to `SimpleRenderer`, which will calculate the NAR hash and
size by downloading the uploaded blobs (and blobs it didn't need to
upload) locally, making such imports faster.
