Clean up virtual functions in html/
https://bugs.webkit.org/show_bug.cgi?id=138166
Reviewed by Andreas Kling.
Clean up virtual functions in html/ by:
- Making virtual functions final when possible
- Making classes final when possible
- Using 'override' when appropriate
- Explicitly marking functions / destructors as virtual when they are
inherently virtual
- Dropping virtual destructors when the class does not have subclasses
and mark the class as final, to get rid of unnecessary vtables
- Making isXXX() virtual functions private on XXX classes to avoid
unnecessary type checks
- De-virtualizing some functions that do not need to be virtual
- Dropping final for virtual functions in classes already marked as
final
No new tests, no behavior change.
