style: Cleanup unused style traversal flags.

Browse source 
Some of these were unused, some of them were only used in combination with
others, so I've unified them.

In particular, Forgetful and ClearAnimationOnlyDirtyDescendants were used only
together for a very specific task (the final animation traversal), so I merged
them into something that has that name.

ClearDirtyBits was unused, so I removed along with some code that would no
longer be called.
