General: Remove `noopener` from links opening in a new tab. 

Removes the automatic addition of `rel="noopener noreferrer"` from links targeting a new tab or window, `target='_blank'`. Since this was introduced, supported browsers have changed their security policies and no longer allow the opened link to have JavaScript access to the previous tab.

Deprecates:

* `wp_targeted_link_rel()`
* `wp_targeted_link_rel_callback()`
* `wp_init_targeted_link_rel_filters()`: converted to a noop function
* `wp_remove_targeted_link_rel_filters()`: converted to a noop function

The deprecated functions are retained in `formatting.php` as in `SHORTINIT` mode the file is included while `deprecated.php` is not.

This also removes the `noopener` from links hard coded within the WordPress dashboard linking to documentation and other resources.

Props audrasjb, azaozz, dhruval04, dorzki, neo2k23, presskopp, sabernhardt, swissspidy, tobiasbg.
Fixes #53843.
