Implement interoperability tests for schema errors (v0.11.0) (webrpc#193)

* Implement interoperability tests for schema errors

* Update test RIDL to be backward compatible with legacy errors

* Regenerate interoperability tests with github.com/webrpc/gen-golang@tags/errors

* Make httpStatus a required field
