URL: https://github.com/apache/arrow-datafusion/issues/10029

   ### Describe the bug
   
   When running a query with `named_struct` in a subquery it fails with an 
error "NamedStructField should be rewritten in OperatorToFunction"
   
   
   ### To Reproduce
   
   
   Reproducer datafusion-cli:
   
   ```sql
   ❯ select (select named_struct('a', 1, 'b', 2)['a']);
   thread 'main' panicked at 
/Users/andrewlamb/Software/arrow-datafusion/datafusion/physical-expr/src/planner.rs:228:21:
   internal error: entered unreachable code: NamedStructField should be 
rewritten in OperatorToFunction
   note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
   ```
   
   Note a similar query works fine
   ```sql
   ❯ select a from (select named_struct('a', 1, 'b', 2)['a'] as "a");
   +---+
   | a |
   +---+
   | 1 |
   +---+
   1 row(s) fetched.
   Elapsed 0.002 seconds.
   ```
   
   
   
   ### Expected behavior
   
   _No response_
   
   ### Additional context
