## Summary

In order to adopt react 19's ref-as-prop model, Flow needs to eliminate
all the places where they are treated differently.
`React.AbstractComponent` is the worst example of this, and we need to
eliminate it.

This PR eliminates them from the react repo, and only keeps the one that
has 1 argument of props.

## How did you test this change?
