Widgets: Introduce Gallery widget for displaying image galleries.
...
* Galleries are managed in the widget in the same way they are managed in the post editor, both using the media manager.
* Gallery widget is merged from the Core Media Widgets v0.2.0 feature plugin and it extends `WP_Widget_Media` in the same way as is done for image, audio, and video widgets.
* Model syncing logic is updated to support booleans and arrays (of integers).
* Placeholder areas in media widgets are now clickable shortcuts for selecting media.
* Image widget placeholder is updated to match gallery widget where clicking preview is shortcut for editing media.

Accessibility: CodeMirror editing areas minor improvements.
...
- properly labels all the code editor areas (Theme/Plugin, Custom HTML widget, Additional CSS), whether CodeMirror is enabled or disabled
- adds `role="textbox"` and `aria-multiline="true"` to the CodeMirror editing area to allow assistive technologies properly identify it as a textarea
- standardizes the "keyboard trap" help text across the admin and keeps it as a list for better readability
- use the Help text elements as target for `aria-describedby`, to make screen readers read out the help text when focusing the editors
- fixes the `aria-expanded` attribute usage in the Customizer "Additional CSS" help toggle
- moves focus to the CodeMirror editing area when clicking on the associated label
- in the Plugin editor screen: changes a `<big>` element to `<h2>` for better semantics and consistency with the Theme editor screen
- also, removes a few textdomain leftovers, see `better-code-editing` and `default`

* Invalidate PHP opcache after file is updated to ensure `include` will ''include'' the written changes.
* Define `WP_ADMIN` when activating plugin in sandbox so plugin code targeting admin will be loaded.
* Do actions that get triggered when loading the admin to ensure plugin code runs that could cause errors on plugin editor screen (and lock out access).
* Fix ability to re-activate a plugin after editing a PHP file other than the main plugin file, and ensure PHP fatal error will be displayed in such cases.
* Consolidate duplicated code into `plugin_sandbox_scrape()` and re-use in `activate_plugin()`.
* Show an error notice instead of a success notice when a file is updated but a plugin was deactivated due to a fatal error.
* Update style of warning when editing an active plugin to be styled as an actual warning notice.

* Code editor control takes the ad hoc code for Additional CSS and makes it reusable and extensible, for Additional CSS in core and plugins to use (such as Jetpack).
* Replace `settings` arg in `wp_enqueue_code_editor()` with separate args for `codemirror`, `csslint`, `jshint`, and `htmlhint`.
* Prefix `codemirror` script and style handles with `wp-` to prevent collisions, as also the object is exported as `wp.CodeMirror` in JS.
* Reduce indent size in Customizer code editor instances and Custom HTML widget to use tab size of 2 instead of 4 to save on space.

Widgets: Improved sidebar mapping on theme switch
...
Builds on efforts brought forward in #17979 .
This will send sidebars through three levels of mapping:
1. If both themes have only one sidebar, that gets mapped.
2. If both themes have sidebars with the same slug, they get mapped.
3. Sidebars that (even partially) match slugs from a similar kind of sidebar will get mapped.
Finally, if the theme has previously been active and we have a record of its
sidebar configuration then, any unmapped sidebar will be restored to its
previous state.
