Shell: Store ListValue's values in a NonnullRefPtrVector<Value>

Browse source 
A ListValue never stores null Values, so it makes sense to restrict it.
This also propagates use of NonnullRefPtr to the create() helpers.
There's a small bit of awkwardness around the use of initializer_list,
since we cannot directly construct a NonnullRefPtrVector from one.
