Victor Sun eca245760a HV: create guest efi memmap for SOS VM ...

The SOS VM should not use host efi memmap directly, since there are some
memory ranges which reserved by hypersior and pre-launched VM should not
be exposed to SOS VM. These memory ranges should be filtered from SOS VM
efi memmap, otherwise it would caused unexpected issues. For example, The
SOS kernel kaslr will try to find the random address for extracted kernel
image in EFI table first. So it's possible that these reserved memory is
picked for extracted kernel image. This will make SOS kernel boot fail.

The patch would create efi memmory map for SOS VM and pass the memory map
info to zeropage for loading SOS VM kernel. The boot service related region
in host efi memmap is also kept for SOS VM so that SOS VM could have full
capability of EFI services as host.
