Andrea Fercia e43633b7d0 Accessibility: Menus: Improve the menu items "Select All".
- changes "Select All" from a link to a checkbox
- the new checkbox is available only when JavaScript support is on
- semantically and for accessibility, a checkbox is a better user interface control because the available action is clear to all users and the selected state is communicated natively
- it's consistent with the existing pattern for the admin tables

Props birgire, audrasjb, afercia.
Fixes #47048.
