Restrict the set of structs for which we generate legacy definitions. (project-chip#24309)

* Restrict the set of structs for which we generate legacy definitions.

Most of the things in af-structs.h are not used, and fixing the names
of some of them causes bad name collisions due to lack of namespacing.
Just stop generating all of them except the ones we really use.

* Address review comment
