Annotate state atoms

Finish annotating state atoms with exclusive state, primary fields, and
default/trigger reset states. These annotations are based off of
ag/4639668.

Some "StateChanged" atoms require more research before annotating them
as state atoms. This includes new atoms that have been added after
ag/4639668 and are potential state atoms.
