Customize: Introduce custom CSS for extending theme styles.

* Custom CSS is associated with a given theme and is displayed in an inline `style` element at the `wp_head` hook after the `wp_print_styles` is called so that it overrides any enqueued stylesheets.
* A `wp_get_custom_css()` function is used for accessing the CSS associated with the current theme (or another theme) and a `wp_get_custom_css` filter for manipulating it.
* CSS is managed in customizer via a new "Additional CSS" section with a single `textarea` control. 
* `WP_Customize_Section::$description_hidden` is introduced for hiding extended descriptions in customizer sections behind a help toggle as done with panels.
* CSS is stored in a `custom_css` post type with the theme (stylesheet) slug as the `post_name`.
* `WP_Customize_Custom_CSS_Setting` is introduced to handle validation of CSS, previewing, and persisting the CSS to the `custom_css` post type.
* The `custom_css` setting is tied to a new `unfiltered_css` capability which maps to `unfiltered_html` by default.
* Escaping the message in the notification template is removed to allow markup (`code` tags) to be rendered.
