 * Fires functions attached to a deprecated filter hook.
 *
 * When a filter hook is deprecated, the apply_filters() call is replaced with
 * apply_filters_deprecated(), which triggers a deprecation notice and then fires
 * the original filter hook.
 *
 * Note: the value and extra arguments passed to the original apply_filters() call
 * must be passed here to `$args` as an array. For example:
 *
 *     // Old filter.
 *     return apply_filters( 'wpdocs_filter', $value, $extra_arg );
 *
 *     // Deprecated.
 *     return apply_filters_deprecated( 'wpdocs_filter', array( $value, $extra_arg ), '4.9', 'wpdocs_new_filter' );
 *
 * @since 4.6.0
 *
 * @see _deprecated_hook()
 *
 * @param string $tag         The name of the filter hook.
