For SEV-SNP guests we need to provide the extended memory. It follows a
very simple layout and very similar to other x86 guests.
First segment: [HIGH_RAM_START - MEM_32BIT_RESERVED_START]
PCI hole: [MEM_32BIT_RESERVED_START - RAM_64BIT_START]
Second segment: [RAM_64BIT_START - RAM_END]

There is no requirement to call copy_from_slice, since all the member
variables are identical and we can directly assign them value.

vmm: Add igvm module and loader module
Add a separate module named igvm to the vmm crate
with definitions to parse and load igvm to the guest memory.
