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.
