EmbeddedPkg: implement EDK2 IoMmu protocol wrapping DmaLib

Browse Source 
Implement a version of the EDK2 IoMmu protocol that is a simple wrapper
around DmaLib. This is intended to be used to wrap NonCoherentDmaLib so
that the generic PCI infrastructure can be used to implement support for
non cache-coherent DMA.
