[NTOS:PNP] Add set functions for debugging PNP and IO managers. (#2457)
Useful functions for debugging IO and PNP managers: PipDumpDeviceNodes() - displays information about a node(s) in the device tree; PipDumpResourceRequirementsList() - displays information about a Io List; PipDumpCmResourceList() - displays information about a Cm List The tree list of devices (DEVICE_NODE structures) is perhaps the main one in the PnP manager. They also store information about the hardware resources required and assigned to devices. These functions can help with debugging. For example, you can call PipDumpDeviceNodes() before and after device enumeration and compare the resulting information. For PipDumpDeviceNodes() it is possible to optionally output: - allocated resources and boot configuration resources - resources required - translated resources It is possible to displays both a single node and the entire tree. Optionally, you can display child nodes. The information output format for resource lists is maximally compressed, since often the only debugging port is a monitor. The DebugLevel parameter allows dumping in two modes: 0 - unconditional; 1 - if NDEBUG is not defined in "debug.c".

If DeviceNode is NULL, then the dump starts at the beginning of the device tree.

Flags is bitmask parametr:

1 - traversal of all children nodes
|

2 - dump allocated resources and boot configuration resources
|

4 - dump resources required
|

8 - dump translated resources
|

DebugLevel: 0 - always dump
|

1 - dump if not defined NDEBUG
