encoding/protojson: fix google.protobuf.Empty serialization

Go Protobuf was diverging from other Protobuf implementations.
Worse: The other Protobuf implementations cannot decode
what Go Protobuf encodes for a google.protobuf.Empty message.

By now, the spec has been updated to explicitly spell out
that google.protobuf.Empty is not considered special and
should result in {"@type": "type.googleapis.com/google.protobuf.Empty"}
without an extra `"value": {}`.

The fixed encoding is decoded correctly with Go Protobuf
v1.35.2 (released November 2024) or newer.

Fixes golang/protobuf#1707

Fixes golang/protobuf#1620
