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.
