RFR: 8263898: (fs) Files.newOutputStream on the "NUL" special device throws FileSystemException: "nul: Incorrect function" (win)

[Brian Burkhalter]

This request proposes to change the native method `WindowsNativeDispatcher.SetEndOfFile()` to succeed even if the Windows function `SetEndOfFile()` returns zero if `GetFileSizeEx()` called on the handle succeeds and reveals a file size of zero.
