Message:

Menus: Support nested array variables in POST data when saving menus.

[36510] allowed larger menus to be created in the Edit Menu screen by JSON-encoding the entire form into a single input field. However, it did not correctly handle nested arrays.

This introduces a new _wp_expand_nav_menu_post_data() helper function to handle this POST data which uses array_replace_recursive() internally. Since the latter is only available on PHP 5.3+, we add a compatibility function to ensure PHP 5.2 support.

Props ericlewis, neverything, swissspidy.
Fixes #36590 for trunk. See #14134.
