[I] Avoid breaking changes for table function args [datafusion]

lewiszlw opened a new issue, #22952:
URL: https://github.com/apache/datafusion/issues/22952

   ### Describe the bug
   
   We encountered several breaking changes for table function arguments. These changes break user-facing SQL.
   
   We have some table functions like `tbf(a='x', b='x')`.
   
   Last time someone added a simplifier to simplify argument expressions. This time someone added a change to coerce argument expressions https://github.com/apache/datafusion/pull/19915 .
   https://github.com/apache/datafusion/blob/d428760d709a375f3d997c84e9c4748a22584149/datafusion/core/src/execution/session_state.rs#L1966-L1999
   
   It seems these changes could be moved into the table function implementation or a method of `TableFunctionArgs::simplified_args()`. We could pass the original argument expressions into the `TableFunctionImpl::call()` method and let users to choose whether to simplify args.
