This PR enables running the features/ipd-setup-step-fast branch for FV3 with SCM by using different implementations of the time vary routines (running over each block=column for SCM, and over all blocks at once for FV3). The PR also contains the PGI changes that went into master already.
Some of the complexity we faced for running the time vary routines over each block separately in FV3 goes away for SCM, since the gcycle -> sfcsub routines are not called (these required the most changes). Hence, gcycle.f90 and sfcsub.F in this branch are the original versions that allow running the time vary steps over all blocks in one go for FV3, and as such cannot be used with SCM.
