Devirtualize several inspector classes destructors

Devirtualize several inspector classes destructors

Devirtualize the following inspector classes destructors:
DOMPatchSupport, InspectorHistory, InspectorState, InspectorStyle and
ScriptProfile.

This avoids creating unnecessary vtables since those classes are never
subclasses nor do they have any virtual function.
