(Go Protobuf currently requires Go 1.21.)

This guarantees correct alignment on stack-allocated values, too.

This commit does not change behavior because the encoding/json
package ignores unexported fields. To encode a Protobuf message
into JSON, users should reach for protobuf/encoding/protojson.

With this change, the generated code (.pb.go files) passes go vet.
I also made the integration test run go vet so that we do not regress.

This is a no-op change in preparation of removing support for weak fields.
It allows users to keep enabling ProtoLegacy in general,
but also disable weak field support independently.

The example message uses the same example names as the Generated Code Reference:

The definition follows the Language Guide:
