Description of Changes:
Contains ccpp/physics code changes from EPIC that are required to upgrade the WM to spack-stack v2.1.0
Tests Conducted:
In progress.
We will be testing the RTs and troubleshooting failing tests with developers. This may lead to separate PRs from those developers to ensure that their tests work with the new stack, esp. LLVM compilers.
Dependencies:
Add any links to parent PRs (e.g. SCM and/or UFS PRs) or submodules (e.g. rte-rrtmgp). For example:
There are related atmos_cubed_sphere and UPP PRs, but there is no dependency between those and CCPP.
