   …functions (#62756)
   
   https://github.com/apache/doris/pull/62756
   
   Multiple BE aggregate and array functions failed at runtime when given 
`TIMESTAMPTZ` input, despite the FE planner accepting the queries. All failures 
shared the same root cause: manually maintained primitive-type dispatch 
switch-cases omitted `TYPE_TIMESTAMPTZ`.
   
   Affected functions and errors:
   
   | Function | Error |
   |----------|-------|
   | `max_by(timestamptz, ...)` / `min_by(timestamptz, ...)` | `Illegal type 
TimeStampTz(6) of argument` |
   | `max_by(..., timestamptz)` / `min_by(..., timestamptz)` | `Agg Function 
max_by(..., timestamptz(6)) is not implemented` | | `array_position` / 
`array_contains` / `countequal` with `Array<TIMESTAMPTZ>` | `execute failed or 
unsupported types for function` |
   | `map_agg_v2(timestamptz, ...)` | `Agg Function ... is not implemented` |
   | `histogram(timestamptz)` | `Agg Function ... is not implemented` | | 
`group_array_intersect(array<timestamptz>)` | `Agg Function ... is not 
implemented` |
   | `group_array_union(array<timestamptz>)` | `Agg Function ... is not 
implemented` |
   
   **`aggregate_function_min_max_by.cpp` / `.h`** — Replace the large 
switch-case in both `create_max_min_value()` and
   `create_aggregate_function_min_max_by()` with
   `dispatch_switch_scalar()`, which covers all scalar types including 
`TYPE_TIMESTAMPTZ` automatically. Only non-scalar cases (`STRING`, `ARRAY`, 
`BITMAP`) are handled separately.
   
   **`function_array_index.h`** — Replace the split
   `dispatch_switch_number()` + datetime if-else + IP if-else dispatch in 
`_execute_dispatch()` with a single `dispatch_switch_scalar()` call.
   
   **`aggregate_function_map_v2.cpp`** — Add `TYPE_TIMESTAMPTZ` to the key-type 
switch.
   
   **`aggregate_function_histogram.cpp`** — Add `TYPE_TIMESTAMPTZ` to 
`creator_with_type_list`.
   
   **`aggregate_function_group_array_set_op_impl.h`** — Replace the large 
nested-type switch-case with `dispatch_switch_scalar()` + `is_string_type()`, 
covering all scalar types including `TYPE_TIMESTAMPTZ` without manual 
enumeration.
