IMPALA-6542: Fix inconsistent write path of Parquet min/max statistics
Quick fix of Parquet write path until the Parquet community
agrees on the ordering of floating point numbers.
The behavior follows the way fmax()/fmin() works, ie. Impala
will only write NaN into the stats when all the values are NaNs.
This behavior is aligned with the quick fix of Parquet-CPP.
Added e2e tests as well.
