PARQUET-1766: [C++] Handle parquet::Statistics NaNs and -0.0f as per upstream parquet-mr Fix an infinite loop when handling NaN values. Refactors the handling of NaNs and other special floating values and clean the unit tests to be readable. The fix uncovered a bug in the Decimal128 arrow-to-parquet path where it would read un-intialized values, i.e. it would always invoke WriteBatch instead of WriteBatchSpaced irregardless of the null count. Thus, the update statistics method would read invalid data.
