feat: add ARRAY_SIZE alias for ARRAY_LENGTH

[ding-young]

I hereby agree to the terms of the CLA available at: https://docs.databend.com/dev/policies/cla/

Summary

• closes feature: Add ARRAY_SIZE alias for ARRAY_LENGTH for Snowflake compatibility #16652

The PR introduces array_size as an alias for length because array_length is already an alias for length.
However, unlike Snowflake, where array_size(non-array) returns NULL,
(ref. https://docs.snowflake.com/en/sql-reference/functions/array_size)
this implementation behaves differently for non-array values since I simply registered array_size as an alias for length.

LGTM, thanks for your contribution. @ding-young
better to add some sqllogic test at this file tests/sqllogictests/suites/query/functions/02_0061_function_array.test

@b41sh I added some sqllogic tests. The PR appears to fail some checks, but I can't determine the reason as the failing tests seem unrelated to the changes I made. Could you help me identify the cause?

This failures seems not related to this PR, I have merge main branch into this PR, and wait the all the CI to run again.
