Message:

General: Remove noreferrer from wp_targeted_link_rel() and other uses.

When noopener noreferrer was originally added in #37941 and related tickets, the noreferrer bit was specifically included due to Firefox not supporting noopener at the time.

Since noopener has been supported by all major browsers for a while, it should now be safe to remove the noreferrer attribute from core.

Props Mista-Flo, audrasjb, joostdevalk, jonoaldersonwp, peterwilsoncc, elgameel.
Fixes #49558.
