Support arrays in type reflection

Tracking issue: rust-lang/rust#146922

This PR adds support for inspecting arrays `[T; N]` through type reflection. It does so by adding `TypeKind::Array` and the `Array` struct:

```rust
pub struct Array {
    pub element_ty: TypeId,
    pub len: usize,
}
```

This can be used to inspect arrays like so:

```rust
match const { Type::of::<[u16; 4]>() }.kind {
    TypeKind::Array(array) => {
        assert_eq!(array.element_ty, TypeId::of::<u16>());
        assert_eq!(array.len, 4);
    }
    _ => unreachable!(),
}
```
