stand/multiboot2: add support for booting a Xen dom0 in UEFI mode
Add some basic multiboot2 infrastructure to the EFI loader in order to be capable of booting a FreeBSD/Xen dom0 when booted from UEFI. Only a very limited subset of the multiboot2 protocol is implemented in order to support enough to boot into Xen, the implementation doesn't intend to be a full multiboot2 capable implementation. Such multiboot2 functionality is hooked up into the amd64 EFI loader, which is the only architecture that supports Xen dom0 on FreeBSD. The options to boot a FreeBSD/Xen dom0 system are exactly the same as on BIOS, and requires setting the xen_kernel and xen_cmdline options in loader.conf.
