RFR: 8285305: Create an automated test for JDK-4495286 [v3]

[Srinivas Mandalika]

> Create an automated test for [JDK-4495286](https://bugs.openjdk.java.net/browse/JDK-4495286)
> 
> AccessibleJTable.setAccessibleSelction should select rows/cols when cell selection.
> When cell selection is not enabled, there is no way, using
> accessibility, to select rows or columns. It seems logical that selecting a cell
> using accessibility should have the same effect as clicking on a cell with the
> mouse. That is, if row or column selection is enabled, then selecting a cell
> should instead cause the row or column to be selected.
>  The proposed test verifies that the above behavior is fixed.
> 
> This review is for migrating tests from a closed test suite to open.
> 
> Testing:
> The test ran successfully on Mach5 with multiple runs (40) on windows-x64, linux-x64 and macos-x64.
