This adds the ability to create an isolate from scratch, except the read only roots, which are initialized from a read_only_data snapshot. To do this we split the heap setup in a read/only part and the rest. The goal of these changes is to later support writing serializer tests, even if the read only roots are static and have to be loaded from a fixed snapshot.
