hypervisor: Avoid leaking KVM GIC state into common GIC state

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.

misc: Adapt consistent import style formatting

Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.

By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

hypervisor: fix building doctests

When doctests are built, the crate is built with itself as a
dependency via --extern. This causes a compiler error if using a
module with the name same as the crate, because it's ambiguous whether
it's referring to the module, or the extern version of the crate, so
it's necessary to disambiguate when using the hypervisor module here.

Fixes running cargo test --doc --workspace.
