Description

Please add JNA binding for Windows IFileDialog in jna-platform:
https://docs.microsoft.com/en-us/windows/win32/api/shobjidl_core/nn-shobjidl_core-ifiledialog

I'm trying to replace JFileChooser with native FileDialog implementations. But for that I need a FileDialog that supports multi-selection for both files and folders, and ideally file-and-folder multi-selection as well (though Windows doesn't seem to support the latter).

Research direction

Start in the jna-platform module and read the linked Windows IFileDialog API documentation alongside existing native bindings. Define the binding scope around native file and folder multi-selection, then verify that the requested selection behavior is supported by the Windows API.
