Install/Uninstall Screen AI library based on usage.
Screen AI library component or DLC was installed or uninstalled based on
feature flags. This would result in downloading the library for all
users once the flags are enabled by default.
To change the behavior, each time the library is used, a pref is saved
which indicates the last used time, and the library is kept on disk and updated for 30 days after the last used time.
