MSHV does not emulate a GICv3-ITS for guests to support MSI interrupts,
instead it exposes a GICv2m device. Currently adding a skeleton code
which would be modified later on with complete implementation.
With this we can start compiling cloud-hypervisor for MSHV on ARM64.
This will make sure that we don't regress in future in terms of basic
compilation test.

we are still using the older way to construct error message. Thus,
migrate to the new approach suggested by the clippy.

KVM supports GICv3-ITS emulation and the current GicState is modelled
around the KVM implementation. We should refactor this to accomodate
other hypervisor requirements. For example, MSHV only support GICv2M
emulation for guests for delivering MSI interrupts instead of GICv3-ITS.

The CLI has grown to a big variety of options. clap prints them in the
help message (--help) in the order they were defined. We now are at a
point where grouping things logically together doesn't work well.
Further, there is no support by clap for logical grouping and the
current code base wasn't consistent. Therefore, this commit introduces
two changes:
- a new structure to define arguments (all in an array)
- an alphabetical ordering of the arguments
No other changes have been made. No options have been altered.
This significantly improves:
- code maintainability and extensibility
- readability of the --help output
A unit test ensures they stay sorted. A better approach to check if the
list of arguments (known at build time) is sorted would be a compile
time check (`const`), but this currently isn't possible in stable Rust.
