Clean up virtual functions in inspector/

[Chris Dumez]

Clean up virtual functions in inspector/ by:
- Making virtual functions final when possible
- Making classes final when possible
- Explicitly marking functions / destructors as virtual when they are
  inherently virtual
- Making isXXX() virtual functions private on XXX classes to avoid
      unnecessary type checks

I never really understood this (moving public virtual functions to private). They are still public, so why not leave it public?

Calling PageConsoleAgent::isWorkerAgent() should give you a compile error now because it *is* private (if the instance is a PageConsoleAgent, not a generic WebConsoleAgent). This makes sure we don't do unnecessary type checks in the code as explained in the Changelog.
