Is your feature request related to a problem? Please describe.
As part of AM5 development, we have decided to transition to using the RTE-RRTMGP radiation framework.

Describe the solution you'd like
A drop-in replacement for the legacy radiation_driver module and its children.

Describe alternatives you've considered
Adding the new radiation scheme in below the radiation driver module level, but it doesn't seem as clean
or leave the new addition self-contained.

Additional context
None at this time.
