Add a property with @name to @jsc_class. 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
#JSCClass 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 #GType to ensure that the instance owned by #JSCClass is used.
If you really want to return a new copy of the boxed type, use #JSC_TYPE_VALUE and return a #JSCValue created
with jsc_value_new_object() that receives the copy as the instance parameter.
