Combine PROD and REPRO build options into 'Release' build type (NCAR#524

)

Combined PROD and REPRO build modes into 'Release' build type. Now only 'Debug' and 'Release' build type are supported.
Both build types must produce bit-for-bit reproducible outputs using different number of threads, mpi tasks, different domain decomposition, have reproducible restarts etc.
