   ### Is your feature request related to a problem or challenge?
   
   - Builds on top #18320
   
   Now that we support `preimage` evaluation we should implement it for udfs to 
enable predicate pruning.
   
   > For example the predicate looking for a particular year
   > 
   > WHERE EXTRACT (YEAR FROM k) = 2024
   > 
   > Can be rewritten as
   > 
   > k >= 2024-01-01 AND k < 2025-01-01.
   > 
   > And then k is easier to pushdown and subject to range analysis, etc.
   
   ### Describe the solution you'd like
   
   Implement `preimage` for `date_part` udf and add sqllogictests.
