x86: enable initial Rust support
Note that only x86_64 is covered and not all features nor mitigations
are handled, but it is enough as a starting point and showcases
the basics needed to add Rust support for a new architecture.

scripts: add `generate_rust_target.rs`
This script takes care of generating the custom target specification
file for `rustc`, based on the kernel configuration.
It also serves as an example of a Rust host program.
A dummy architecture is kept in this patch so that a later patch
adds x86 support on top with as few changes as possible.
