URL: https://github.com/apache/arrow-rs/issues/1856

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   `PrimitiveArray::from_iter` currently always initializes and returns a null_buffer, even when all values are valid.
   
   **Describe the solution you'd like**
   
   Before constructing the `ArrayData` we could check the count of ones in the validity buffer and mapping it to None if all values are valid. This should not add any overhead as the number of nulls is counted anyway by the `ArrayData` constructor.
