Script Loader: Do not normalize absolute paths in inline block styles CSS.

`_wp_normalize_relative_css_links()` used to normalize all non-absolute URLs regardless of whether it's a relative path or an absolute path. The normalization should only happen for relative paths (paths without a leading `/`) and not for absolute paths.

Reference: [https://www.rfc-editor.org/rfc/rfc1808#section-4 RFC 1808, Section 4, Step 4].

Follow-up to [52036], [52695], [52754], [55658], [55669].

Props scholdstrom.
