RFR: JDK-8218681 : Windows exe's generated by jpackage have wrong info

[Alexander Matveev]

Please review the jpackage fix for bug [1] at [2].

This is a fix for the JDK-8200758-branch branch of the open sandbox 
repository (jpackage).

- User provided version was not display, because it was added as 
additional LANG_ENGLISH resource and Windows Explorer was displaying 
default one added during build as LANG_NEUTRAL. Fixed by 
adding/modifying version information as LANG_NEUTRAL resource.
- Removed unused fields from WinLauncher.template.
- Improved error handling for version swap.
- Fixed debug build after JDK-8212091 by removing not needed code from 
#ifdef DEBUG.
