Remove the SmbiosTablePublishEntry() function from "SmbiosPlatformDxe.c". "SmbiosPlatformDxe.c" becomes hypervisor-agnostic. Add SmbiosTablePublishEntry() back, simplified for QEMU, to the existent file "Qemu.c". The GetQemuSmbiosTables() function no longer needs to be declared in "SmbiosPlatformDxe.h"; "SmbiosPlatformDxe.h" becomes hypervisor-agnostic. Add SmbiosTablePublishEntry() back, renamed and simplified for Xen, to the new, arch-independent file "Xen.c". (The existent Xen-specific C files are arch-dependent.) Update both INF files; remove the dependencies that are now superfluous in each.
