Windows: Add mount option that allows mounting a volume without attaching it to the specified drive letter. This is useful in situation where Windows has issue with the filesystem (e.g. ReFS on Windows 10 1809) and we need to use third party software to be able to use the filesystem under Windows through low level VeraCrypt virtual device (e.g. \Device\VeraCryptVolumeX).
