Abstract common invocations of "cargo", that do not require copying
the generated bindgen file or setting up MESON_BUILD_ROOT.
In the future these could also do completely without cargo and invoke
the underlying programs directly.

Right now, using cargo with QEMU requires copying by hand the bindings.rs to the
source tree. Instead, we can use an include file to escape the cage of cargo's
mandated source directory structure.
By running cargo within meson's "devenv" and adding a MESON_BUILD_ROOT
environment variable, it is easy for build.rs to find the file. However, the
file must be symlinked into cargo's output directory for rust-analyzer to find
it.

offset_of! was stabilized in Rust 1.77.0. Use an alternative implemenation
that was found on the Rust forums, and whose author agreed to license as
MIT for use in QEMU.
The alternative allows only one level of field access, but apart
from this can be used just by replacing core::mem::offset_of! with
qemu_api::offset_of!.
The actual implementation of offset_of! is done in a declarative macro,
but for simplicity and to avoid introducing an extra level of indentation,
the trigger is a procedural macro #[derive(offsets)].
The procedural macro is perhaps a bit overengineered, but it helps
introducing some idioms that will be useful in the future as well.

Add rust/qemu-api, which exposes rust-bindgen generated FFI bindings and
provides some declaration macros for symbols visible to the rest of
QEMU.
