RFR: 8366852: java/awt/Choice/ChoiceMouseWheelTest/ChoiceMouseWheelTest.java test is failing [v2]

[Alexander Zvegintsev]

> There are several major issues with the test:
> 
> 1. The `frameExited` variable is set to true when the mouse pointer exits the frame. The test does not expect this to happen with the first mouse click on the `choice` when the mouse pointer is already over the test frame (frame mouseExited - > choice mouseEntered). A reset for the frameExited was added.
> 2. The test does not wait for the frame to appear after the call to `setVisible()`, so the test can start operating not on a fully visible window (e.g. one with an appearance animation). A delay has been added.
> 3. In macOS, the direction of rotation of the mouse wheel is different, which was not taken into account. 
> 
> Testing looks good.
