RFR: 8332901: Choice/SelectCurrentItemTest/SelectCurrentItemTest.java doesn't open popup on macOS [v2]

[Alexey Ivanov]

> I looked at `java/awt/Choice/SelectCurrentItemTest/SelectCurrentItemTest.java`, ran it and noticed that the test does not open the popup of the `Choice` component on macOS 14.x.
> 
> If the popup does not open, the test does not verify anything — it always passes.
> 
> I refactored the test and added a mouse listener to the `Choice` component. If mouse click isn't registered, the test fails.
> 
> The updated test fails for me locally on macOS Sonoma 14.5. This is likely the result of [JDK-8322653](https://bugs.openjdk.org/browse/JDK-8322653): _[macos14] : Mouse clicks are not received within 3 pixels of the window boundary_.
> 
> The updated test passes on CI.
