[I] to_timestamp() fails when passed mix of scalar and array args [datafusion]

["neilconway (via GitHub)" <gi...@apache.org>]

neilconway opened a new issue, #20223:
URL: https://github.com/apache/datafusion/issues/20223

   ### Describe the bug
   
   When to_timestamp() was invoked with a scalar Float64 and an array of strings, the previous coding neglected to broadcast the scalar to the array properly when producing the return value.
   
   ### To Reproduce
   
   ```
   CREATE TABLE t61(v2 STRING);
   INSERT INTO t61(v2) VALUES ('flX'), ('3');
   
   SELECT TO_TIMESTAMP(123.5, tt0.v2) FROM t61 AS tt0;
   ```
   
   Yields
   
   ```
   Internal error: UDF to_timestamp returned a different number of rows than expected. Expected: 2, Got: 1
   ```
   
   ### Expected behavior
   
   _No response_
   
   ### Additional context
   
   _No response_
