Migrate the Windows native file-system refresh monitor to JNA

This avoids the native code necessary for JNI and consequently the
separate o.e.core.resources.win32.x86_64 fragment, while being only
slightly slower without noticeable impact on the overall performance.
At the same time it allows to use the 'Win32RefreshProvider' on all CPU
architectures supported on Windows out of the box.
