Implement Yul to LLVM IR compilation benchmarks (#407)

# Description

Closes [#404](https://github.com/paritytech/revive/issues/404)

Adds compilation time benchmarks for:

* Parsing of Yul source code -> AST Object
* Lowering of AST Object -> LLVM IR (unoptimized)

The benchmarks can be run from the root via:

```sh
# Run all benchmarks in the revive-yul crate (parsing + lowering)
make bench-yul
```

HTML reports will be generated under `target/criterion`, and a summary
of the results at
[crates/yul/BENCHMARKS_PARSE_M4PRO.md](https://github.com/paritytech/revive/blob/lj/compilation-benchmarks-yul/crates/yul/BENCHMARKS_PARSE_M4PRO.md)
and
[crates/yul/BENCHMARKS_LOWER_M4PRO.md](https://github.com/paritytech/revive/blob/lj/compilation-benchmarks-yul/crates/yul/BENCHMARKS_LOWER_M4PRO.md)
(currently from running on a Mac M4 Pro).
