Add ability to ignore tests at runtime

[yanganto]

This is an issue to be ignored in Rust for the long term.
rust-lang/rust#68007

Also, there is already a PR for this.
rust-lang/rust#96574

Could we consider adding it in Crab lang? 🦀

I am new here but I think i can give it a try if it's ok for you guys ?

[yanganto]

It is happy to see this and also looks after the following PRs. But I do not really know if the Crab is ready to make any difference between Rust.
