URL: https://github.com/apache/datafusion/issues/25417

   ### Describe the bug
   
   A DISTINCT aggregate call that passes the same expression as more than one 
argument fails during optimization with an internal error.
   
   ### To Reproduce
   
   ```
   -- OK
   SELECT corr(DISTINCT x, y) FROM (VALUES (1.0, 2.0), (2.0, 5.0), (3.0, 4.0)) 
AS t(x, y);
   
   -- Fails
   SELECT corr(DISTINCT x, x) FROM (VALUES (1.0, 2.0), (2.0, 5.0), (3.0, 4.0)) 
AS t(x, y);
   
   Optimizer rule 'single_distinct_aggregation_to_group_by' failed
   caused by
   Internal error: Assertion failed: args.len() == 1 (left: 2, right: 1): 
DISTINCT aggregate should have exactly one argument.
   ```
   
   ### Expected behavior
   
   _No response_
   
   ### Additional context
