Pxl 527eb5b059 [Enchancement](function) nullable inline refactor of min_max_by/bitmap && add register_functio… (#17228)
1. nullable inline refactor of min_max_by/bitmap/group_concat/histogram/topn
2. add register_function_both method
3. add datetimev2 type creator of min_max_by
4. remove uint16/32/64 in FOR_INTEGER_TYPES
