Add a property with name to this.
When the property value needs to be getted, getter is called receiving the the class instance as first parameter and
user_data as last parameter. When the property value needs to be set, setter is called receiving the the class
instance as first parameter, followed by the value to be set and then user_data as the last parameter. When the property is
cleared in the Class context, destroy_notify is called with user_data
as parameter.
Note that the value returned by getter must be transfer full. In case of non-refcounted boxed types, you should use
g_type_pointer instead of the actual boxed Type to ensure that the instance
owned by Class is used. If you really want to return a new copy of the boxed type, use
JSC_TYPE_VALUE and return a Value created with
Value.object that receives the copy as the instance parameter.
