PHP Notice: Array to string conversion in admin ajax points.

Requests similar to the following trigger a PHP Notice:

PHP Notice:  Array to string conversion in ...

While it would be possible for a plugin to be expecting wp_ajax_Array or admin_post_Array to be fired. I don't see these as valid or remotely expected use-cases though.

Additionally, this applies the changes in response-code to the admin-ajax endpoint in [41120] & [41926] to the admin-post endpoint.

In 52813:

Administration: Require a valid action parameter to be set for admin-ajax.php requests.

This avoids Array to string conversion PHP notices when an array is passed as the action parameter.

Additionally, send an appropriate HTTP response status code when an invalid action is passed to admin-post.php.

Follow-up to [13175], [19738], [41120], [41926].

Props dd32.
Fixes #55212.
