Rollup merge of #98994 - kons-9:dont_use_process_exit, r=jyn514

replace process exit with more detailed exit in src/bootstrap/*.rs

Fixes [#98830](https://github.com/rust-lang/rust/issues/98830)

I implemeted "detail_exit.rs" in lib.rs, and replace all of std::process::exit.
So, error code should panic in test code.
```
// lib.rs
pub fn detail_exit(code: i32) -> ! {
    // Successful exit
    if code == 0 {
        std::process::exit(0);
    }
    if cfg!(test) {
        panic!("status code: {}", code);
    } else {
        std::panic::resume_unwind(Box::new(code));
    }
}
```
