Improvements to support OS specific customization for JDK internal use: - To select values and code; allowing elimination of unused code and values - Optionally evaluated by build processes, compilation, or archiving (i.e. CDS) - Simple API to replace adhoc comparisons with `os.name` - Clear and consistent use across build, runtime, and JDK modules The PR includes updates within java.base to use the new API.
