Support nextest

[gitmalong]

💡 Feature description

cargo test does not has any test progress indicator so it would be great to see nextest integrated for better dev experience.

According to the maintainers of nextest it should be not so difficult to integrate nextest-rs/nextest#952

Maintainer of nextest here, happy to help if there are any issues! For Miri it was dead simple: rust-lang/miri#2398

In particular, I noticed this bullet point at https://github.com/rustwasm/wasm-bindgen/blob/main/crates/test/README.md:

Running each test in its own wasm instance to avoid poisoning the environment on panic

that you would get for free with nextest.
