Adding the ability to invalidate caches to force metadata collection

This adds the discussed hack to touch `clippy_lints/src/lib.rs` to invalidate cargos cache and force metadata collection. I've decided to use the [`filetime`](https://github.com/alexcrichton/filetime) crate instead of the touch command to make is cross-platform and just cleaner in general. Looking at the maintainers I would say that it's a save crate to use xD.

fixes #1594

changelog: Add ``[`needless_bitwise_bool`]`` lint

Creates a new `bitwise_bool` lint to convert `x & y` to `x && y` when both `x` and `y` are booleans. I also had to adjust thh `needless_bool` lint slightly, and fix a couple failing dogfood tests. I made it a correctness lint as per flip1995's comment [here](https://github.com/rust-lang/rust-clippy/pull/3385#issuecomment-434715723), from a previous WIP attempt at this lint.

acdf43f257 Auto merge of #7225 - InquisitivePenguin:unnessecary-async, r=llogiq
New lint: `unused_async`

changelog: Adds a lint, `unused_async`, which checks for async functions with no await statements

`unused_async` is a lint that reduces code smell and overhead by encouraging async functions to be refactored into synchronous functions.

Fixes #7176

### Examples

```rust
async fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Could be written as:

```rust
fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Something like this, however, should **not** be caught by clippy:
```rust
#[async_trait]
trait AsyncTrait {
    async fn foo();
}

struct Bar;

#[async_trait]
impl AsyncTrait for Bar {
    async fn foo() {
        println!("bar");
    }
}
```

Stop linting `else if let` pattern in [`option_if_let_else`] lint

For readability concerns, it is counterproductive to lint `else if let` pattern.

6bbee5c584 Auto merge of #7217 - xFrednet:7172-metadata-collection-cargo-alias, r=flip1995
Add `cargo collect-metadata` as an cargo alias for the metadata collection lint

This PR adds a new alias to run the metadata collection monster on `clippy_lints`. I'm currently using it to create the `metadata_collection.json` file and I plan to use it in the `deply.sh` script. Having it as a new alias enables us to simply use:

```sh
cargo collect-metadata
```

It sometimes requires running `cargo clean` before collecting the metadata due to caching. I'm still debating if I should include a cargo clean as part of the `run_metadata_collection_lint` test or not. Input on this would be greatly appreciated 🙃

That's it, just a small change that can be reviewed and merged in parallel to #7214.

See: #7172 for the full metadata collection to-do list or to suggest a new feature in connection to it.
