Allow the extension NBLS to launch on Windows arm64 with x64 JDK

The NBLS launch on Windows arm64 is fixed to use the x64 version of
nbcode exe launcher.
- This will allow the use of the extension on this platform with
  jdk.jdkhome set to an x64 JDK.
- If the user programs need to be run on an arm64 JDK, the
  jdk.project.jdkhome can be set to the arm64 JDK.
- Note: Currently there is no arm64 windows build of the nbcode
  launcher.
