RFR: 8284524: Create an automated test for JDK-4422362 [v4]

[Srinivas Mandalika]

> Create an automated test for [JDK-4422362](https://bugs.openjdk.java.net/browse/JDK-4422362)
> 
> The BoundedRangeModel components (JScrollBar, JSlider, JProgressBar) return
> BoundedRangeModel.getMaximum() from getMaximumAccessibleValue() in their
> AccessibleValue implementation.
> The real maximum value (due to the constraints on BoundedRangeModel) is
> model.getMaximum() - model.getExtent().
> 
> The test verifies that the above is adhered to as expected.
> 
> This review is for migrating tests from a closed test suite to open.
> 
> Testing:
> The test ran successfully on Mach5 with multiple runs (30) on windows-x64, linux-x64 and macos-x64.
