Add a sentinel proto.Error error which matches all errors returned by packages in this module. Document that protoregistry.NotFound is an exact sentinel value for performance reasons. Add a Wrap function to the internal/errors package and use it to wrap errors from outside sources (resolvers). Wrapped errors match proto.Error. Fixes golang/protobuf#1021.
