Merge feature/capgen into main as of 2024-03-08

[climbfuji]

Update main from feature/capgen as of 2024-03-08 (includes optional argument updates in feature/capgen).

The only commit on top of the merge is https://github.com/NCAR/ccpp-framework/pull/546/commits/6cdd38a032d89d0f79c66f37f0c7172e59f135cd, which is required to parse the metadata in the Unified Forecast System / ccpp-physics (underscores in units, e.g. degree_north).

User interface changes?: No

Fixes: Working towards https://github.com/NCAR/ccpp-framework/issues/540 (need the changes to the metadata parser to implement optional arguments in ccpp_prebuild)

Testing: capgen

• in ./test: ./pylint_test.sh works and gives "similar" results as before (see #547)
• in ./test: ./run_fortran_tests.sh all pass
• in scripts: python3 -m doctest *.py no errors prebuild
• in ./test_prebuild: test_mkstatic.py works
