Incorrect file permissions when building linux or osx packages in Windows

Current/Missing Behaviour

Any Linux or macOS packages built from Windows will have incorrect permissions set for executable files. These need the +x bit set, but this is stripped off when extracting files in Windows.

Expected/Proposed Behaviour

Either find a way to preserve the +x bits for all NW.js files (and anything else packaged with the app) or show a warning to users that osx and linux packages should not be built from Windows.

Additional Info

• Operating System: Windows
• Node version: 18.12.0
• NW.js version: 0.70.1
• Repro link: Any linux or osx build in Windows

[sysrage]

Based on several conversations, there is likely no good way to keep permissions set properly while building in Windows. We should probably just list this limitation in the documentation and suggest that users build in WSL or a VM. A warning can also be shown if users attempt an osx or linux build in Windows.
