ARROW-10817: [Rust] [DataFusion] Implement TypedString and DATE coercion

This PR adds support for what the `sqlparser` crate calls `TypedString` which is basically syntactic sugar for an inline-cast. As this was an effort to get the `TPC-H` queries behaving correctly I then went a step further and added support for `Date` (temporal) coercion. I can split this PR if needed.

```sql
where
    l_shipdate <= date '1998-09-02'
```

is equivalent to

```sql
where
    l_shipdate <= CAST('1998-09-02' AS DATE)
```

FYI I am planning to tackle `INTERVAL` next.

Closes #8892 from seddonm1/typed_string
