   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   DataFusion doesn't allow Dictionaries or LargeStringArrays in like comparison operations.  This functionality is already included in Arrow.
   
   **Describe the solution you'd like**
   
   Arrow provides operations on StringArray / LargeStringArray, or DictionaryArray with values StringArray / LargeStringArray, with support for comparisons against another array or a scalar.  The current `Like` implementation doesn't support all of these combinations.  In addition, the check in the physical expressions doesn't use coercion rules when validating the request.
