RFR: 8285373: Create an automated test for JDK-4702233 [v2]

[Srinivas Mandalika]

> Create an automated test for [JDK-4702233](https://bugs.openjdk.java.net/browse/JDK-4702233)
> 
> Several new AccessibleRole and AccessibleRelation constants are needed in those classes in the java.accessibility package. These new contants codify additions made in the GNOME, Netscape, and UNO (StarOffice) accessibility APIs.
> StarOffice 6.1 and GNOME accessibility require new role, state and relation
> constants in the javax.accessibility package. The existing constants are
> inadequate for providing accessibility to StarOffice and GNOME applications
> as required by Section 508.
> 
> Solution
> --------
> Define new constants in the javax.accessibility package.
> AccessibleRelation
> AccessibleRoles
> AccessibleState
> AccessibleAction
> AccessibleContext
> 
> The test validates the public fields of the above AccessibleConstants.
> 
> 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.
