3ce0fef7fd build: Bump vmm-sys-util crate and its consumers
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].

[2] https://github.com/rust-vmm/kvm-ioctls/pull/223
[3] https://github.com/cloud-hypervisor/versionize_derive/tree/ch-0.1.6

Fixes: #6072

556bda74a0 hypervisor: emulator: Use wrapping add for memory offset
Assume rax is 0xfee003e0 and the displacement is negative 0x60. The effective
address is then 0xfee00380. This is perfectly valid.

Example instruction:
c7 40 a0 00 10 00 00    movl   $0x1000,-0x60(%rax)

b6d009830d hypervisor: x86: Emulator is only needed on mshv, not kvm
On x86-64, when the underlying hypervisor platform is KVM, no
instruction emulator is necessary. KVM handles instruction boundaries
internally.

This change allows to skip the iced-x86 dependency on KVM, improving
build times, prunes the dependency graph and reduces network traffic
during the initial build.

For Hyper-V, the emulator is still necessary on x86-64, so nothing
changes there.
