Reviewed by Wenson Hsieh.

When determining if a keyboard scroll may occur, consult the value of `-[UIScrollView allowsKeyboardScrolling]`,
a new API introduced in iOS 17.

The default value of this property is `NO` on iPhone, and `YES` on iPad, Catalyst, and Vision. As such, the
property must initially be set to `YES` in WKScrollView to maintain its existing behavior.

Also adds an API test for this behavior.
