 Script Loader: Refine hoisted stylesheet ordering to preserve original CSS
 cascade in classic themes.

 This introduces placeholder inline `STYLE` tags in the `HEAD` which are
 used to accurately locate hoisted styles which were printed in the footer.
 This improves the robustness of the hoisting logic. A style placeholder
 had been used previously in the inline style for `wp-block-library` for
 placing core block styles, and new placeholders are added for global
 styles and non-core block styles.

 Furthermore, this fixes the cascade for inline styles added to `wp-block-
 library`. When separate block styles are not used, these styles would have
 appeared after the single combined `wp-block-library`. However, in 6.9 the
 order changed so that separate block styles would appear after. To
 preserve the original cascade, this splits the `wp-block-library` inline
 style: the first half (likely just the inlined `block-library/common.css`)
 appears before the block styles, and the remainder appears in a new `STYLE
 #wp-block-library-inline-css-extra` element.
