Speedup CI (#842)

- Remove `tools: cross` input to `actions/just-setup`
    since we use `cargo-zigbuild` for cross compiling instead of `cross-rs`
    now.
 - Only install `cargo-zigbuild` in `just ci-install-deps` if `JUST_USE_CARGO_ZIGBUILD` is enabled
 - Include hash of `rustc -vV` in `build-cache`
    Switching between different versions of `rustc` will cause all crates to be
    rebuilt using new `rustc`.
 - Replace input `cache` with `index-cache` and `build-cache` in `actions/just-setup`
    for better control of caching behavior
 -  Reuse workflow `test`'s `build-cache` in workflow `lint`
