Jakob Gruber e7e10aa70c [snapshot] Sanitize isolate during serialization 
The isolate snapshot must not contain context-dependent objects, thus
root visitation must not reach context-dependent objects. This CL
sanitizes the isolate around serialization by clearing & later
restoring two lists: 1. feedback vectors for profiling tools, 2.
detached contexts.

Drive-by: Set an array buffer allocator for
SerializeDeserializeAndVerify.
Drive-by: Allow serialization of *another* native context when
serializing a native context.
