RFR: 8284524: Create an automated test for JDK-4422362

[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.
