[SDK] Introduce the PO GUID library

This library aims to include all the public and global power manager related GUID identifiers into one shared library, of which they can be accessed across multiple modules of ReactOS, e.g. the kernel, ACPI, PCI, et al.

This patch is needed for the development of the Power Manager (#5719) to continue.
