Query: Ensure that the page parameter is scalar in WP_Query::get_posts().

The `page` query var only accepts a scalar value and passes the value through functions that assume a scalar value.

Adding an extra guard condition does not affect its functionality but does avoid a PHP fatal error for `trim()` when a non-scalar value such as an array is passed.

Follow-up to [2535], [53891].
