A major improvement to the developer experience of clippy in
Cloud Hypervisor.

2. Simplify adding new lints

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].

As almost every sub crate depends on thiserror, lets upgrade it to a
workspace dependency.

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.

Rust 2021 edition has a few improvements over the 2018 edition. Migrate
the project to 2021 edition by following recommended migration steps.
Luckily, the code itself doesn't require fixing.
Bump MSRV to 1.56 as it is required by the 2021 edition. Also fix the
clap build dependency to make Cloud Hypervisor build again.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.
