 Customize: Enable Customizer live previews of Custom CSS in Block Themes.

 In a Block Theme, the Custom CSS from the Customizer is inserted into the
 global styles, before the global style's Custom CSS. In order to update
 the Customizer's Custom CSS inside of the global styles, milestone CSS
 comments are added in the preview so that the live preview logic can do
 the replacement.

 Follow-up to [55192], [58703].
 See #57536, #61395.
