feat: add cargo pkgid support for cargo-script (#14961)

### What does this PR try to resolve?

close #14831

In this PR, we added the `cargo pkgid` support for the cargo-script.

For the package itself:

```console
cargo pkgid --manifest-path foo.rs
path+file:///my-project/foo.rs/foo#0.86.0
```

For its dependence:

```console
cargo pkgid --manifest-path foo.rs -p sqlx
registry+https://github.com/rust-lang/crates.io-index#[email protected]
```

### How should we test and review this PR?

I have updated the unit tests and also added more test cases for it.

### Additional information

None
