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

[NTOS:IO][NTOS:PNP] Implement PiCallDriverAddDevice
- Move the driver's name obtaining logic into the IopGetDriverNames
  function
- Create a new PiCallDriverAddDevice instead of PipCallDriverAddDevice
  and move it to pnpmgr/devaction.c file. Move around all its internal
  helpers too
- Support a proper Windows-compatible driver loading order for a PDO
  (lower filters, main service, upper filters, etc.)
- Set a correct Problem for the DeviceNode, in case of an error during
  driver loading
- Check the Start Type for all drivers before loading
- Do not try to load drivers during the early boot stage when there is
  no disk subsystem initialized

[NTOS:PNP][NTOS:IO] Do not create a device object + node on every driver load
- Remove the usage of IopCreateDeviceNode and change it to
  PipAllocateDeviceNode where required

[NTOS:PNP] Improve and refactor PnP notifications
- BUGFIX: do not call IoGetRelatedTargetDevice while guarded mutex is acquired
  (the function issues an APC, but they are disabled inside a critical section)
- BUGFIX: only the beginning of a structure for GUID_PNP_CUSTOM_NOTIFICATION was copied and queued.
  Just pass it as-is to a subscriber, without copying
- Don't convert event GUID to string, store and compare GUID struct itself
- Split IopNotifyPlugPlayNotification into 3 functions for each type of notification
  (less stack usage and for future changes)
- Move initialization code for notifications into a separate routine
- Use separate lists and locks for every type of notification
- Put "TargetDeviceChange" notifications into their place inside DEVICE_NODE
