bors 17edacef07 Auto merge of #113026 - jieyouxu:run-make-v2, r=bjorn3
Introduce `run-make` V2 infrastructure, a `run_make_support` library and port over 2 tests as example

## Preface

See [issue #40713: Switch run-make tests from Makefiles to rust](https://github.com/rust-lang/rust/issues/40713) for more context.

## Basic Description of `run-make` V2

`run-make` V2 aims to eliminate the dependency on `make` and `Makefile`s for building `run-make`-style tests. Makefiles are replaced by *recipes* (`rmake.rs`). The current implementation runs `run-make` V2 tests in 3 steps:

1. We build the support library `run_make_support` which the `rmake.rs` recipes depend on as a tool lib.
2. We build the recipe `rmake.rs` and link in the support library.
3. We run the recipe to build and run the tests.

`rmake.rs` is basically a replacement for `Makefile`, and allows running arbitrary Rust code. The support library is built using cargo, and so can depend on external crates if desired.

The infrastructure implemented by this PR is very barebones, and is the minimally required infrastructure needed to build, run and pass the two example `run-make` tests ported over to the new infrastructure.

### Example `run-make` V2 test

```rs
// ignore-tidy-linelength

extern crate run_make_support;

use std::path::PathBuf;

use run_make_support::{aux_build, rustc};

fn main() {
    aux_build()
        .arg("--emit=metadata")
        .arg("stable.rs")
        .run();
    let mut stable_path = PathBuf::from(env!("TMPDIR"));
    stable_path.push("libstable.rmeta");
    let output = rustc()
        .arg("--emit=metadata")
        .arg("--extern")
        .arg(&format!("stable={}", &stable_path.to_string_lossy()))
        .arg("main.rs")
        .run();

    let stderr = String::from_utf8_lossy(&output.stderr);
    let version = include_str!(concat!(env!("S"), "/src/version"));
    let expected_string = format!("stable since {}", version.trim());
    assert!(stderr.contains(&expected_string));
}
```
