@FelixYBW Before this PR, Gluten will try to pushdown them, but throw
`Subfield filters creation not supported for input type **`, which make
FileSourceScan fallback to Vanilla Spark.
After this PR, Gluten will not try to pushdown them.
BTW, `short_decimal_field` is supported to pushdown, the other three fields
don't.
