Add four more color schemes to round out our collection at eight.

The new schemes are Ectoplasm, Coffee, Ocean, Sunrise. For those following along, the first three were at one point named Ghostbusters, Pixel, and Cape Cod.

See [26137] for the original color schemes.

Core updates for the new color schemes.
 * Update about page, there's now 8.
 * Display them four wide, not three, and ensure adequate spacing.
 * Use a dedicated nonce.
 * Push Light to the front in addition to Default.
 * Use user-profile.js on about.php. A few extra things are initialized but they are harmless.

Freedoms/Credits: Allow for big first paragraphs, overridden by the font-size change in [26719]. Reduced slightly to prevent wrapping on freedoms.

Admin color schemes: Manually handle RTL and minified versions of the CSS files on registration.

This bypasses WP_Styles entirely, which is much simpler for the moment, given that color schemes bypass WP_Styles for plenty already. The script loader is told to stop thinking of colors.css as an RTL-ified file. The colors-fresh handle, used directly on the login screen, needed to be (even before this commit).

fixes #26316.

Cron: Fix a case where a cache inconsistency can cause wp_clear_scheduled_hook() to enter an infinite loop. This unravels the function from using other cron api functions to looping over the cron array directly. See #25773
