OvmfPkg: Generate CloudHv as a PVH ELF binary
Following the model from the Xen target, CloudHv is generated as a PVH
ELF binary to take advantage of the PVH specification, which requires
less emulation from the VMM.
The fdf include file CloudHvElfHeader.fdf.inc has been generated from
the following commands:
$ gcc -D PVH64 -o elf_gen OvmfPkg/OvmfXenElfHeaderGenerator.c
$ ./elf_gen 4194304 OvmfPkg/CloudHv/CloudHvElfHeader.fdf.inc
