UDF/UDAF/UDWF: refactor ReturnType #8182

Def one UDF:

my_udf(expr, 'return_type')

Using:

case1:

my_duf(col, 'UInt32')

Return Type is:
DataType::UInt32

case2:

my_duf(col, 'UInt64')

Return Type is:
DataType::UInt64

At present, the above udf cannot be realized through the ReturnTypeFunction. This is because the ReturnTypeFunction provides only the data types of the input parameters.
