Auto merge of #17923 - basvandriel:feature/build-before-restart-debug, r=Veykril

Building before a debugging session was restarted

# Background
Resolves #17901. It adds support for rebuilding after debugging a test was restarted. This means the test doesn't have to be aborted and manually re-ran again.

# How this is tested
First, all the Visual Studio Code extensions are loaded into an Extension Host window. Then, a sample test like below was ran and restarted to see if it was correctly rebuild.

```rust
#[test]
fn test_x() {
    assert_eq!("1.1.1", "1.1.0");
}
```
