[SPARK-3904] [SQL] add constant objectinspector support for udfs
In HQL, we convert all of the data type into normal `ObjectInspector`s for
UDFs, most of cases it work, however, some of the UDF actually requires the
input `ObjectInspector` to be the `ConstantObjectInspector`, which will cause
exception.
e.g.
select named_struct("x", "str") from src limit 1;
