RFR: 8295670: Remove duplication in java/util/Formatter/Basic*.java [v2]

[Justin Lu]

> Issue: Duplication of methods between Basic*.java test classes, due to auto generation by genBasic.sh
> 
> Fix: Reorganize parts of Basic-X.java.template into base class in Basic.java. Toggled -nel flag for generation script (genBasic.sh) to remove excessive white space. Moved a previous direct change to BasicDateTime.java into the template.
> 
> Note: Main files to look at are Basic.java and Basic-X.java.template, as the rest are a reflection of the auto generation
