Initializes and sets value from an instantiatable type via the
value_table's collect_value() function.
Note: The value will be initialised with the exact type of
instance. If you wish to set the value's type to a different GType
(such as a parent class GType), you need to manually call
gobject.value.Value.init_ and gobject.value.Value.setInstance.
