[Following] Duckdb generates decimal fields of a parquet based on int

[liun03]

Based on concept https://duckdb.org/docs/sql/data_types/numeric.html#fixed-point-decimals: We sense the decimal type in duckdb is based on int.

BUT, there are some decimal issues with int based values: https://issues.apache.org/jira/browse/HIVE-21987

We need to follow the issues and hive 4.x fixed the issues.(alpha version)
