   Initial plan
   
   step 1: able to plan
   - Find all supported keywords and register operator tables.
     - `FilterKind` enum, `TransformFunctionType` enum & aliases, `@ScalarFunction` annotated names
   - add test for usage in V2 for plan compilation and plan resolution
   
   step 2: able to run
   with step 1 we are still unable to run every combination of the SQL operator, but the design from here can be flexible, options to consider.
   - either mimic the predicate/transform/scalar categorizes 
   - register all possible in/out types aliases mapping back to impl
   - create scalar functions for each missing pieces. 
   
   This issue should address step 1 and consider #9641 for best approach for step 2
