Based on #19708. This is on the path to porting the entire event class to Rust, as `event.content` will then return the new Rust class `JsonObject`. This PR adds a pure Rust `JsonObject` class that is a `Mapping` representing a json-style object. It uses `serde_json::Value` as its in-memory representation and `pythonize` for conversion when a field is looked up on the object. I'm not thrilled with the name, but couldn't think of a better one. This also adds `JsonObject` handling to the JSON serialisation functions we use, as well as to the `freeze(..)` function. Reviewable commit-by-commit.
