Describe the enhancement requested

The previous patch[1] has allowing Decimal32/Decimal64 type in arrow. However, Parquet has poor support for them now. We need more testing and test for it.

We now have store_decimal_as_integer. This should also working for decimal32/decimal64.

[1] #43957

Component(s)

C++, Parquet
