Implemented the prefers-reduced-transparency media query for all platforms. Windows and Mac have specific settings which are used, others (Android and Linux/GTK) have it enabled if prefers-reduced-motion is also enabled as there is no dedicated setting to check. Locked behind new pref `layout.css.prefers-reduced-transparency.enabled`, off by default always for now. Also added new WPT tests (none previously).
