Message:

Widgets: Use isset() in WP_Widget:: display_callback() to support ArrayIterator and ArrayObject.

[33696] introduced support returning ArrayIterator and ArrayObject objects from WP_Widget::get_settings().

Per the PHP manual, array_key_exists() stopped supporting this in PHP 8.0.0 and deprecated in PHP 7.4.0.

For backward compatibility reasons, array_key_exists() will also return true if key is a property defined within an object given as array. This behaviour is deprecated as of PHP 7.4.0, and removed as of PHP 8.0.0.

This commit uses isset() instead of array_key_exists() which is supported on all current versions of PHP.

Includes unit tests.

Ref:

• ​https://www.php.net/manual/en/function.array-key-exists.php#refsect1-function.array-key-exists-notes

Follow-up to [32602], [33696].

Props dlh, hellofromTonya, jrf, sergeybiryukov.
Fixes #52728.
