api config: add build rules for go protos (#7987)

Some BUILD files are missing build rules to generate go protos. envoyproxy/go-control-plane depends on these protos, so they should be exposed publicly. Added build rules to generate *.pb.go files.

Risk Level: Low
Testing: These rules were copied to google3 and tested internally. Unfortunately, I am having a bit of trouble with bazel build directly on these targets ("Package is considered deleted due to --deleted_packages"). Please let me know if there is a better way to test this change.
