Adds dependencies on the gRPC & protobuf libraries, and implements Nix code to generate the C++ sources from the included proto definitions. This is theoretically supported via CMake, but practically doesn't work and I don't care to debug why. Doing it like this lets us instead add a CMake library target for our proto definitions based on the sources generated by Nix. Pros: * no need to deal with the gRPC CMake mess * it works! Cons: * iteration requires nix-shell restart Change-Id: Ie1fe9807fc96c49cb8f7161ba59d093456062b15 Reviewed-on: https://cl.tvl.fyi/c/depot/+/927 Tested-by: BuildkiteCI Reviewed-by: isomer <isomer@tvl.fyi>
