RFR: 8155939: sun.launcher.LauncherHelper INSTANCE is unused

[Claes Redestad]

Hi,

sun.launcher.LauncherHelper is currently a singleton enum class, but the 
INSTANCE is never used. With encapsulation in place we shouldn't worry 
about cleaning this up.

jdeps data show no usage of this helper class outside of the JDK.

Bug: https://bugs.openjdk.java.net/browse/JDK-8155939

Thanks!
