[TASK] Improve type annotations for ExpressionBuilder::literal()

PHPStan will (correctly) unify the previous type
`\PDO::PARAM_*|Connection::PARAM_*|int` to `int` (because
`\PDO::PARAM_*` as well as `Connection::PARAM_*` are all
ints).

So we're using the stricter `Connection::PARAM_*` now, which is a
superset of `\PDO::PARAM_*`.

This allows PHPStan to catch calls to this method with
incorrect values.
