vmm: support PCI I/O regions on all architectures

While non-Intel CPU architectures don't have a special concept of IO
address space, support for PCI I/O regions is still needed to be able
to handle PCI devices that use them.

With this change, I'm able to pass through an e1000e device from QEMU
to a cloud-hypervisor VM on aarch64 and use it in the cloud-hypervisor
guest. Previously, it would hit the unimplemented!().

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.

This patch bumps the following crates, including `kvm-bindings@0.7.0`*,
`kvm-ioctls@0.16.0`**, `linux-loader@0.11.0`, `versionize@0.2.0`,
`versionize_derive@0.1.6`***, `vhost@0.10.0`,
`vhost-user-backend@0.13.1`, `virtio-queue@0.11.0`, `vm-memory@0.14.0`,
`vmm-sys-util@0.12.1`, and the latest of `vfio-bindings`, `vfio-ioctls`,
`mshv-bindings`,`mshv-ioctls`, and `vfio-user`.

* A fork of the `kvm-bindings` crate is being used to support
serialization of various structs for migration [1]. Also, code changes
are made to accommodate the updated `struct xsave` from the Linux
kernel. Note: these changes related to `struct xsave` break
live-upgrade.

** The new `kvm-ioctls` crate introduced breaking changes for
the `get/set_one_reg` API on `aarch64` [2], so code changes are made to
the new APIs.

*** A fork of the `versionize_derive` crate is being used to support
versionize on packed structs [3].
