 This patch introduces a new argument to the `register_post_type()`
 function which will list a custom post type in the 'At a Glance' widget.

 A few notes:
 - For backwards compatibility reasons the new argument is set to false by
 default.
 - If no menu_icon argument is set, then it will default to `dashicons-
 marker`. This is the same behaviour as previous.
 - I've added menu_icon arguments to the core post/page post_types. I'm not
 sure if this has any negative implications.
 - Removed a small chunk of unnecessary CSS where the dashicons were
 hardcoded into the styling rather than using the existing `.dashicons`
 classes. (Related #27414)
 - `wp_dashboard_quota()` was slightly refactored due to the removal of
 some of the CSS.
