CI: update actions to run on Node 16

[miles170]

Partial fix for #1156.

1. update actions/checkout to v3
2. remove use of actions-rs/cargo

   actions-rs is currently inactive and has an issue like Node.js 12 actions are deprecated. Please use Node.js 16 actions-rs/cargo#216

3. remove use of actions-rs/toolchain

   actions-rs is currently inactive and has an issue like Node.JS 12 deprecation on GitHub Actions actions-rs/toolchain#219

4. add use of Swatinem/rust-cache

All tests are passed, as you can see here. (https://github.com/miles170/fd/actions/runs/3457767586)

One thing that I think we lose from using the actions-rs actions is caching between different builds. I don't know how much of a difference that would make for this.

I checked the code and it never uses actions-rs/toolchain rustc_hash before.

You could use https://github.com/Swatinem/rust-cache for caching

@tmccombs Would you like to let me try rust-cache in this PR or issue another PR?

[tmccombs]

I'm fine with either.

1. CI first runs without cache.
2. CI second runs with cache.

We must place Rust cache after Install cross otherwise, Post Rust cache calculated hash will mismatch.
See https://github.com/Swatinem/rust-cache/blob/master/src/config.ts#L94-L102
