13ef424bf1 vmm: Add IGVM to the config/commandline
This patch adds igvm to the Vm config and params as well as
the command line argument to pass igvm file to load into
guest memory. The file must maintain the IGVM format.
The CLI option is featured guarded by igvm feature gate.

The IGVM(Independent Guest Virtual Machine) file format
is designed to encapsulate all information required to
launch a virtual machine on any given virtualization stack,
with support for different isolation technologies such as
AMD SEV-SNP and Intel TDX.

At a conceptual level, this file format is a set of commands created
by the tool that generated the file, used by the loader to construct
the initial guest state. The file format also contains measurement
information that the underlying platform will use to confirm that
the file was loaded correctly and signed by the appropriate authorities.

The IGVM file is generated by the tool:

The IGVM file is parsed by the following crates:
