Message:

Themes: Inline render blocking CSS `classic-themes.css'

Since [54358], a new CSS file classic-themes.css is enqueued on all pages on the front end of themes without theme.json. This is a blocking http request, the impact on performance will be affected by network conditions. Inlining this style, stops this blocking request. By adding style data of path to the registered style, the function wp_maybe_inline_styles will automatically inline the style for us.

Props spacedmonkey, adamsilverstein.
Fixes #58480.
