CORE-15575
In addition, fix a PartitionId assignment copy-paste error in PartitionCreateDevice().
The returned standard UniqueId has the following format:
- Basic volume on MBR disk: disk Mbr.Signature + partition StartingOffset (length: 0x0C)
- Basic volume on GPT disk: "DMIO:ID:" + Gpt.PartitionGuid (length: 0x18)
- Volume on Basic disk (NT <= 4): 8-byte FTDisk identifier (length: 0x08)
- Volume on Dynamic disk (NT 5+): "DMIO:ID:" + dmio VolumeGuid (length: 0x18)
- Super-floppy (single-partition with StartingOffset == 0),
or Removable media: DiskInterfaceName.
- As fallback, we use the VolumeInterfaceName.

- Implement IOCTL_VOLUME_QUERY_VOLUME_NUMBER:
See usage example in:
7241cebfa2/mayfield/branches/spr/src/umapps/ndassvc/service/drivematch.cpp (L627)
- Stubplement IOCTL_VOLUME_IS_PARTITION:
The only type of volume we support right now is disk partition
so we just return success. A more robust algorithm would be
to check whether the volume has only one single extent, that
covers the whole partition on which it lies upon. If this is
not the case, return STATUS_UNSUCCESSFUL instead.
This driver works as complement to disk.sys/classpnp.sys from Windows 10
Manages partition PDOs and exposes them as volumes to mountmgr.sys.
The driver is almost complete, just some minor IOCTLs missing (will be
added on demand)
