Add override annotations consistently

This makes it easier to follow class hierarchies and understand where a
class is changing the interface. I hit this when I found a class that
had the annotation on some methods it was overriding, but not all, which
made it confusing.

Prepares for adding the lint rule and enforcing it.

40% of overridden methods were annotated - add annotations to the remaining 60%.
