protobuf-go-lite: keep protoc-gen-go, drop unused, fix linter errors

vtprotobuf generates static code for Marshal and Unmarshal. We just need a
version of protoc-gen-go that does not import reflect nor any of the "heavy"
protobuf packages that add a lot of complexity to the resulting binary.

tinygo-org/tinygo#2667

Drop all unused code and fix linter warnings.
