Subject: [PATCH] REST API: Add wp_is_numeric_array helper function

The API uses this to do special operations on list responses (used
for collections), so we need to detect whether an array is
associative or numeric-indexed.

After much discussion, the bikeshed is to be painted green and gold.

See #33982.
