Support FixedSizeList in `ScalarValure::try_new_null`

[wjones127]

Is your feature request related to a problem or challenge?

When scanning a Parquet file with a FSL column, we get the the following error if that column is in the projection:

NotImplemented("Can't create a scalar from data_type \"FixedSizeList(Field { name: \"element\", data_type: Float32, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, 768)\"")

Describe the solution you'd like

I think this should simply be a matter of adding an impl here:

https://github.com/apache/arrow-datafusion/blob/ca260d99f17ef667b7f06d2da4a67255d27c94a9/datafusion/common/src/scalar.rs#L2867-L2876

However, we should also test end-to-end that we can roundtrip these columns to Parquet files.

In #14558 the API changed, let me update the title accordingly

	// `ScalaValue::FixedSizeList` contains single element `FixedSizeList`.
	DataType::FixedSizeList(field_ref, fixed_length) => {
	ScalarValue::FixedSizeList(Arc::new(FixedSizeListArray::new_null(
	Arc::clone(field_ref),
	*fixed_length,
	1,
	)))
	}

Do we still want to add that parquet roundtrip test to close this out @wjones127 ?

Honestly that’s probably sufficient. We can close this.
