Subject: [PATCH] Multisite: Escape urls and html elements in wp-activate.php

When WPMU was merged in [12603], the intent was to go back and make sure everything was escaped. This completes that intent.

Props rafiq91, rajinsharwar, costdev, oglekler, nicolefurlan, ryan, peterwilsoncc.
Fixes #57336.
See #11644.
