[I] Support dict encoded structs in `get_field` [datafusion]

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

brancz opened a new issue, #21113:
URL: https://github.com/apache/datafusion/issues/21113

   ### Is your feature request related to a problem or challenge?
   
   Our schema contains dictionary encoded structs, and when we want to write a statement like:
   
   ```
   SELECT mystruct.myfield FROM mytable;
   ```
   
   This errors.
   
   ### Describe the solution you'd like
   
   I want to be able to query my schema, to do that we need support for resolving dict accesses in `get_field`.
   
   ### Describe alternatives you've considered
   
   Casting the column to its non-dict encoded self, this is what we do right now just to get it to work, but obviously that's a bad idea for performance.
   
   ### Additional context
   
   Already have the implementation, this is just for tracking.
