Message:

Clear update caches when site language is changed.

The update screen has a re-install button which could show the wrong language locale after the site language was changed. That's because the update data is cached.
Introduce _wp_clear_update_cache() as a helper function to clean up the update cache.

props SergeyBiryukov, ocean90.
fixes #30369.
