feat(tools/depot-scanner): init project r/1683

depot-scanner is a tool that runs Nix and parses the --trace-file-access output to deduce what files are necessary to evaluate a derivation.

Take DEPOT_ROOT from the environment. If depotRoot doesn't exist, print an error early.

Fix the build of the protobuf library. Switch to the GRPC build rule, as a service is in this proto file.

Create the PathType enum and parse it from cmdline flags.
