In the style of #30947 and default-filters.php, add 2 new files to wp-admin/includes:

`admin-filters.php`
`ms-admin-filters.php`

There are random actions and filters littered among files like `misc.php`. These files contain functions that won't work outside of admin context and are typically only loaded in files that have already loaded the admin bootstrap.

See #32529.
