Debug version of the UncachedMemoryAllocation lib that uses the VirtualUncachedPages
protocol, produced by the DXE CPU driver, to produce debuggable uncached memory buffers.

The DMA rules for EFI contain the concept of a PCI (DMA master) address for memory and
a CPU (C code) address for the memory buffer that don't have to be the same. There seem to
be common errors out there with folks mixing up the two addresses. This library causes
