Review comment:
Don't we need also compare other members?
* `Children` when it is `NestedType`
* `ByteWidth` when it is `FixedSizeBinaryType`
I suppose we need to create a new `ArrowType` comparer for the product
projects like `ArrayTypeComparer` of `Apache.Arrow.Tests` and use it.

Review comment:
Do we need this `Dispose()`?
How about using `using` statement and delete this line if we need to dispose?
```
using RecordBatch recordBatch = TestData.CreateSampleRecordBatch(length: 1);
```

Review comment:
How about creating a new test method for this case?
