Source/WebCore:

NetworkResourcesData now stores a raw pointer to CachedResource.
CachedResource now notifies InspectorInstrumentation that it will be destroyed.
InspectorInstrumentation stores a set of InstrumentingAgents and broadcasts willDestroyCachedResource event to all available resourceAgents.
Destroyed resources content is saved to NetworkResourcesData.
