While I'm working on this, should needless_borrow be split into two? One lint for expressions and another for patterns. In expression it only lints when the compiler inserts a dereference, but for patterns it's whenever a double reference is created. I think at least the case where a double reference is needed should be split into a new lint as it's not 'needless', it can just be done without a ref binding.

For illustration:

```rust
fn foo(x: &&str) {}

match Some("test") {
    // ref binding is useless here
    Some(ref x) => *x,
    _ => (),
}

match Some("test") {
    // ref binding is useless here
    Some(ref x) => x.len(),

}

    // double reference is needed, but could be `Some(x) => foo(&x)`

Adding the default lint level to the metadata collection

I noticed while working on the website adaption that the lint groups still had the `clippy::` prefix in the JSON output. This PR removes this prefix and adds a `level` field to each lint and with that simplifies the website display and saves performance.

The deprecated lints get are assigned to the level `none`. This is a bit different in comparison to the current lint list, but I believe that this will look better overall. Unless there is any argument against this :).

That's it just a small baby PR in comparison to the original monster ^^

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");
    }
}

Metadata collection monster searching for Clippy's configuration options

This PR teaches our lovely metadata collection monster which configurations are available inside Clippy. It then adds a new *Configuration* section to the lint documentation.

---

The implementation uses the `define_Conf!` macro to create a vector of metadata during compilation. This enables easy collection and parsing without the need of searching for the struct during a lint-pass (and it's quite elegant IMO). The information is then parsed into an intermediate struct called `ClippyConfiguration` which will be saved inside the `MetadataCollector` struct itself. It is currently only used to generate the *Configuration* section in the lint documentation, but I'm thinking about adding an overview of available configurations to the website. Saving them in this intermediate state without formatting them right away enables this in the future.

The new parsing will also allow us to have a documentation that spans over multiple lines in the future. For example, this will be valid when the old script has been removed:
```rust
/// Lint: BLACKLISTED_NAME.
/// The list of blacklisted names to lint about. NB: `bar` is not here since it has legitimate uses
(blacklisted_names: Vec<String> = ["foo", "baz", "quux"].iter().map(ToString::to_string).collect())
```

The deprecation reason is also currently being collected but not used any further and that's basically it.

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:
