Short-circuits directive processing when the markup does not actually contain any `data-wp-*` attributes.
This reduces function calls and memory usage for the best case scenario due to not involving `WP_HTML_Tag_Processor`.

Props joemcgill, swissspidy, gziolo, cbravobernal, flixos90.
Fixes #60749.
