Creates a Proxy over an Invocation that behaves like a plain object.
The returned Proxy supports property access, in, Object.keys(), spread,
and JSON.stringify(). If the host implements setArgument and deleteArgument,
property assignment and deletion delegate to those methods (preserving any
validation they perform). Otherwise, those operations throw a TypeError.
