Fixed#1038
sccache is not very effective at caching dependencies, the external
C/C++ is recompiled in every ci and it takes a lot of time.
Compilation of other Rust dependencies also takes quite some time and
sccache is not helping at all, so I decided to switch to
`Swatinem/rust-cache@v2`.
The downside of the new caching method is that a new cache conntaining
part of the `.cargo/` and `target/` will be created whenver
`Cargo.lock`/`Cargo.toml` changes, but it can still reuse the old cache
to create new caching.
This is acceptable given that `sccache` often fails to reuse
cache due to rate limiting from GHA, since it is not designed for use
like a s3 object pool, and `sccache` will create a lot of new cache
artifacts for a given branch that cannot be reused in main and would
have to cleanup via a cronjob.
Edit:
rust 1.70 uses llvm 16.0, however ubuntu-latest still uses llvm 15.0
As such, during release-build, cross-lang-lto failed due to llvm is too
old.
Temporarily disable linker-plugin-lto to fix this.

Remove `mozilla-actions/sccache-action@v0.0.2` and instead use `taiki-ie/install-action` to install `sccache`, since we already use `taiki-e/install-action` for installing crates.
This PR also refactor just-setup.yml and use pass `GITHUB_TOKEN` to `taiki-e/install-action` which uses `cargo-binstall` for installing `cargo-auditable` and `sccache`.

- 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`
