[inspector] improved Runtime.queryObjects

- simplify prototype traversal.
- use V8InspectorClient::isInspectableHeapObject since some embedders
  on JavaScript heap contains not inspectable objects, e.g. wrapper
  boilerplates in blink.
- Runtime.queryObjects takes prototype object as argument for more
  flexibility.
