rust: repurpose qemu_api -> tests

The crate purpose is only to provide integration tests at this point,
that can't easily be moved to a specific crate.

It's also often a good practice to have a single integration test crate
(see for ex https://github.com/rust-lang/cargo/issues/4867)

Drop README.md, use docs/devel/rust.rst instead.
