[NTOS:PNP] Implement NT5.2-like DEVICE_NODE state management

Browse source 
- Use DeviceNode->State field and its values, instead of
  DeviceNode->Flags for tracking current node state
- Change DNF_* flags to the ones compatible with Windows XP+
- Simplify state changes for device nodes and encapsulate all the logic
  inside the PiDevNodeStateMachine routine. This makes the ground for
  future improvements in the device removal sequence and
  resource management
- Now values inside DeviceNode->State and ->Flags are compatible with
  the windbg !devnode macro and can be tracked using it
- BUGFIX: fixed cases where IRP_MN_START_DEVICE or
  IRP_MN_QUERY_DEVICE_RELATIONS may be sent to a device after a
  IRP_MN_REMOVE_DEVICE
