AX: Implement relevant simulated key presses for custom ARIA widgets for increment/decrement
https://bugs.webkit.org/show_bug.cgi?id=213744

Reviewed by Darin Adler.

Source/WebCore:

In order to allow custom ARIA widgets to work, we can post keyboard events for specific ax actions
that are not handled natively.

Spec: https://github.com/WICG/aom/blob/gh-pages/explainer.md#user-action-events-from-assistive-technology

Test: accessibility/keyevents-posted-for-increment-actions.html
