internal/cmd/generate-protos: generate test for testdata

Running "go build ./..." does not descend into testdata directories.
However, the testdata in this repository is source code that is
intended to build properly. We could rename the directory, but that does
not test whether the generated packages can initialize properly.

Thus, we generate a trivial test that simply blank imports all packages.

Doing this reveals that some of the generated files have incorrect imports,
leading to registration conflicts.

To avoid introducing a dependency on gRPC from our go.mod file, we put
the testdata directories in their own module. Also, we avoid running
internal/testprotos through the grpc plugin because the servie and method
definitions in that directory are more for testing proto file initialization
rather than testing grpc generation.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
