061351d82d build: upgrade whole* workspace to Rust edition 2024 
This upgrades the Cargo workspace to Rust edition 2024 to keep the
code base clean and up to date.

The commit only contains the adjustments to the Cargo.toml files and
basic compiler error fixes. Also, this commit includes new SAFETY
comments as discussed in [1]. The changes were not automatically
fixed by `cargo fix --edition` but needed manual adjustments.

Apart from that, all formatting and clippy adjustments follow in
subsequent commits.

*
As only exception, workspace member net_gen sticks to edition 2021
for now as discussed in [0].

eb0b14f70e misc: vhost_user_block: streamline #[source] and Error 
This streamlines the code base to follow best practices for
error handling in Rust: Each error struct implements
std::error::Error (most due via thiserror::Error derive macro)
and sets its source accordingly.

This allows future work that nicely prints the error chains,
for example.

So far, the convention is that each error prints its
sub error as part of its Display::fmt() impl.

88a9f79944 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.

As per VirtIO spec 1.2 section 5.2.6, the `status` field is a byte, not
u32. cloud-hypervisor writes an `u32` to guest memory, which
accidentally zeros out the following 3 bytes, and may corrupt guest OS
internal state.

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].
