[core] ensure AutoMount is enabled while the app is running

Browse source 
* Having AutoMount disabled when a Fixed drive is being used can
  result in a failure during formatting (issue #386).
* Also set explicit FILE_ATTRIBUTE_NORMAL flag an normalize CreateFile usage
* Closes #386

* The following methods get or set the AutoMount setting (which is different from AutoRun)
* Rufus needs AutoMount to be set as the format process may fail for fixed drives otherwise.
* See https://github.com/pbatard/rufus/issues/386.
*
* Reverse engineering diskpart and mountvol indicates that the former uses the IVdsService
* ClearFlags()/SetFlags() to set VDS_SVF_AUTO_MOUNT_OFF whereas mountvol on uses
* IOCTL_MOUNTMGR_SET_AUTO_MOUNT on "\\\\.\\MountPointManager".
* As the latter is MUCH simpler this is what we'll use too
