RFR: JDK-8217317 : Create jpackage native library for windows

[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).

- jpackage launcher will now build same as Linux and OS X using 
SetupBuildLauncher.
- jpackage.dll was added based on Windows jpackage.exe launcher which 
will have icon swap and version swap functionality called via JNI.
- Some code formatting, clean up and minor improvements where done to 
icon and version swap code. No functional changes.
- Windows registry will be read and enumerated via JNI as well.
- isDirectoryInExclusionPath() will use native path comparison, since 
paths in registry and temp folder returned by Java code can be in short 
or long format, thus simple string comparison will not work.
- Windows Defender workaround warning will be checked for --build-root 
as well if it is set.
- Removed extra escaping from JPackageHelper for Windows, otherwise 
tests fails due to incorrect escaping. Our launcher used CreateProcess 
to launch java.exe by passing args from main() to CreateProcess. This is 
why I think we required extra escaping.
