Interactivity API: Directives cannot derive state on the server 

The Interactivity API has a concept of "derived state" but it only worked on the client (JavaScript). This is the implementation that mirrors it, so derived state has good server-side solution.

Props jonsurrell, darerodz, gziolo, luisherranz, cbravobernal.
Fixes #61037.



Built from https://develop.svn.wordpress.org/trunk@58327
