RFR: 8295239: Refactor java/util/Formatter/Basic script into a Java native test launcher

[Justin Lu]

Issue: Formatter unit tests are launched via basic.sh

Fix: Replace basic.sh with a Java test launcher

Note: Java.internal.math was included in the original configuration of Basic, 
but I removed it as it was not used within the Basic unit tests
