Andrea Fercia d35be7a120 Administration: Admin menu: Use `aria-current` for the current active page.
The `aria-current` attribute is a simple, effective way to communicate to assistive
technologies which the current item within a set of items is. While the admin menu
structure isn't 100% ideal (the top-level item is repeated also as a sub-item)
adding `aria-current="page"` to the sub-items gives an important feedback to
assistive technologies users.

This change introduces `aria-current` for the first time in core. Worth noting
there are other places where it can be used to improve accessibility. These should
be addressed in separate tickets and patches.

Fixes #41589.

Andrea Fercia a4ae97437b Administration: Thickbox: Fix conflicts with the Plugin details and native Thickbox modals.
The Plugin details modal custom implementation in the Plugins page conflicts with
other Thickbox instances added by plugins. Thickbox shows its age and has been
modified over time to suit core needs. However, WordPress should do its best to
not create conflicts with the native Thickbox styles and functionalities. Plugin
authors should be able to use `add_thickbox()` in any admin page as documented, 
without having to worry about potential errors.

- fixes a JavaScript error when closing a native Thickbox modal in the Plugins page
- avoids to override the native Thickbox modal styles
- uses a CSS class to target the Plugin details modal and remove a pile of overqualified CSS selectors

Fixes #41417.

Weston Ruter 9b5d71bad0 Widgets: Add dirty state tracking for widgets on admin screen.
* Mark a widget as dirty when a field input triggers a `change` or `input` event; clear dirty state when widget is successfully saved.
* Disable Save button and re-label "Saved" when widget not dirty.
* Show AYS dialog when leaving widgets admin screen with unsaved changes.
* When widgets are dirty, expand all unsaved widgets at AYS check and focus on first one.
* Change "Close" link to "Done"; hide link when widget is dirty and reveal when saved.
* The "Done" link persistently appears in the Customizer even after making a change (when the widget is dirty) because changes are autosaved into the changeset.
* Prevent saving widget when form fails `checkValidity`.
* Fix frequency of triggering of `change` event on the rich Text widget's `textarea` limited now to when there are actual changes.
* Add a class of `widget-dirty` to widget containers when the widget has unsaved changes.

John Blackbourn c7a79b0e6a Plugins: Introduce singular capabilities for activating and deactivating individual plugins.
This introduces the following meta capabilities:

* `activate_plugin`
* `deactivate_plugin`
* `deactivate_plugins`

The singular `activate_plugin` and `deactivate_plugin` capabilities are used along with the corresponding plugin name when
determining whether or not a user can activate or deactivate an individual plugin.

The plural `deactivate_plugins` capability is used in place of the existing `activate_plugins` capability when determining
whether a user can deactivate plugins.

Each of these new meta capabilities map to the existing `activate_plugins` primitive capability, which means there is no
change in existing behaviour, but plugins can now filter the capabilities required to activate and deactivate individual
plugins.

The new meta capabilities are called `install_languages` and `update_languages`. Prior to this change, there were no proper capability checks applied.

In addition to being generally more verbose, the new capabilities make it possible for example to allow a user to update languages, but nothing else. By default they fall back to the original way of how they were handled.

Andrea Fercia a029f83fb5 Menus: Visually hide the menu item edit link text in a consistent way.
Fixes a visual glitch visible on Ubuntu. WordPress uses system fonts and they have
different metrics across operating systems. Uses screen-reader-text as a more
solid way to visually hide text.

Props punit5658, afercia.

Felix Arntz 7e2ca92e69 Multisite: Introduce a `can_add_user_to_blog` filter to prevent adding a user to a site.
Under certain circumstances, it can be necessary that a user should not be added to a site, beyond the restrictions that WordPress core applies. With the new `can_add_user_to_blog` filter, plugin developers can run custom checks and return an error in case of a failure, that will prevent the user from being added.

The user-facing parts and the REST API route that interact with `add_user_to_blog()` have been adjusted accordingly to provide appropriate error feedback when a user could not be added to a site. Furthermore, two existing error feedback messages in the site admin's "New User" screen have been adjusted to properly show inside an error notice instead of a success notice.

Props jmdodd.
Fixes #41101.
