streamline maps_embedded

### Replacing Maps Service `openapi-internal.yaml` With gRPC

These are all the endpoints used by the validator.  The plan is to delete `service_internal` and create `validator_controller` with equivalent gRPC functionality.  This can then be extended in the future for public api & maptest integration by creating new grpc endpoints that the public api & game-rpc talk to.  The gRPC extensions would be separate files (`mapfixes.proto`, `submissions.proto`, `maps.proto`) unlike `validator.proto` which has a bunch of dedicated endpoints that only the validator should use.

### Why?

To reduce the number of exposed apis.  Without this there would need to be 4 (!) exposed apis (validator openapi, web openapi, public api, gRPC for game-rpc), with it, only 2 (web api, gRPC).

### Why didn't you do this in the first place?

I didn't know how.  I think I have a handle on it now.
