Editor: Improve performance of WP_Theme_JSON class by reducing usage of expensive array functions.

Browse Source 
In many scenarios array functions are more expensive than using simpler `for` or `foreach` loops.

This changeset results in roughly 4% faster `wp_head` execution time for both block themes and classic themes. While this may seem like a small win, it is a worthwhile enhancement and only one part of several other little performance tweaks which are being worked on to improve performance of `theme.json` parsing further.

Props aristath, desrosj, jrf, spacedmonkey.
Fixes #56974.
See #57067.
