Message:

Script Loader: Prevent fatal error in load-styles.php.

Duplicates the code of get_theme_file_path() within wp_theme_has_theme_json(). This is to account for the load-styles.php context in which the former function is unavailable.

Follow up to [56073].

Props SergeyBiryukov, oglekler, spacedmonkey, joemcgill, dd32.
Fixes #57629.
