Implement binding for list types

[ozars]

This PR enables implementing ToSql for types that represent lists. Below example starts working:

#[derive(Debug, PartialEq, Eq)]
struct MyList(Vec<i32>);

impl ToSql for MyList {
    fn to_sql(&self) -> crate::Result<ToSqlOutput<'_>> {
        Ok(ToSqlOutput::Owned(Value::List(
            self.0.iter().map(|&x| Value::Int(x)).collect(),
        )))
    }
}

let db = Connection::open_in_memory()?;
db.execute_batch("CREATE TABLE foo (numbers INT[]);")?;

let list = MyList(vec![1, 2, 3, 4, 5]);
db.execute("INSERT INTO foo (numbers) VALUES (?)", params![&list])?;

This code works by inferring inner data type of a list from the first element of the list.

This means below code doesn't work since this method doesn't work for empty lists unfortunately:

let list = MyList(vec![]);

// This should panic because the list is empty and DuckDB cannot determine the type of the list.
_ = db.execute("INSERT INTO foo (numbers) VALUES (?)", params![&list]);

There are also a breaking change in ValueRef::List so that conversion from Value::List is possible. Without this change, ValueRef::List assumes referee is backed by an Arrow array, while Value::List is backed by Vec<Value>, preventing a conversion.
