[fix](array_avg) fix core for array_avg (#46927)

[amorynan]

if we set session variable for fold_constant_for_be = 1 and enable_decimal256 = true
here will meet error in sql

SELECT ARRAY_AVG(CAST([] AS ARRAY < DECIMALV3(1,0) > ));

with core

[hello-stephen]

Thank you for your contribution to Apache Doris.
Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

1. What problem was fixed (it's best to include specific error reporting information). How it was fixed.
2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
3. What features were added. Why was this function added?
4. Which code was refactored and why was this part of the code refactored?
5. Which functions were optimized and what is the difference before and after the optimization?
