[PATCH v6 3/8] OvmfPkg: Xen: Generate fdf include file from ELF header generator

["Boeuf, Sebastien" <sebastien.boeuf@intel.com>]

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

Updating the fdf include file based on the run of the ELF header
generator. The diff from this patch is the result of:

$ gcc -o elf_gen OvmfPkg/OvmfXenElfHeaderGenerator.c
$ ./elf_gen 2097152 OvmfPkg/XenElfHeader.fdf.inc
