38794	Customize: Allow panels and sections to have notifications just like controls can	westonruter	westonruter	"In #34893, the ability to show notifications on controls was added. In #35210 this is proposed to be extended at a global level to be able to show notifications at the root of the customizer. Between these two ends, there should also be the ability to show notifications at the panel and section level. 

The Customize Posts plugin implements notifications for sections which could serve as a start for the patch here: https://github.com/xwp/wp-customize-posts/blob/0.8.2/js/customize-post-section.js#L825-L942

Once implemented, section notifications should be utilized for the Header Media section to show a notification when not previewing a URL that is eligible for a header video. See #38778. The section-level notification could be used in #40432 as well.
