Merge clippy and clippy (wasm) jobs on CI (#5447)

## Summary

The clippy wasm job rarely fails if regular clippy doesn't, wasm clippy
still compiles a lot of native dependencies for the proc macro and we
have less CI jobs overall, so i think this an improvement to our CI.

```shell
$ CARGO_TARGET_DIR=target-wasm cargo clippy -p ruff_wasm --target wasm32-unknown-unknown --all-features -j 2 -- -D warnings
$ du -sh target-wasm/*
12K	target-wasm/CACHEDIR.TAG
582M	target-wasm/debug
268M	target-wasm/wasm32-unknown-unknown
```
