Better error message from CCPP in case call to ccpp_physics_run for group 'fast_physics' failed

Description

As the title says: Better error message from CCPP in case call to ccpp_physics_run for group 'fast_physics' failed. Without this change, the actual error message that is written to cdata%errmsg by the physics is not written to stderr and then user only gets "Call to ccpp_physics_run for group 'fast_physics' failed".

How Has This Been Tested?

ufs-weather-model regression tests (see ufs-community/ufs-weather-model#850)

@bensonr If you think this is a good idea, I can pull #146 into this PR.

I don't think it's necessary. They both touch different files, so there is no need to bundle them together. I am mostly waiting for reviews for the various PRs that have come in recently.
