clamp or fail - mpas and wrf model_mod have this, it is ignored by dart

[hkershaw-brown]

I don't think clamp_or_fail is used: ☠️ https://github.com/NCAR/DART/blob/52e6e45f8f6ff07a90227766c8de72f1474162f2/models/wrf/model_mod.f90#L343

https://github.com/search?q=repo%3ANCAR%2FDART%20clamp_or_fail&type=code

clamp_or_fail not passed to state structure No fail in clamp_variable
