Implement CCPPized check_energy_chng and check_energy_fix

[jimmielin]

Closes #1138

Purpose of changes

• CCPPize check_energy_chng and check_energy_fix
  CAM interfaces have been kept in check_energy.F90 instead of a new module because check_tracers is not yet CCPPized, there are other non-CCPPized routines in module, and for compatibility with FV3 external calls
• Save air_composition cp_or_cv_dycore into state snapshot
• Separate out "energy_formula_physics"/"energy_formula_dycore" definitions used in get_hydrostatic_energy from dyn_tests_utils "vcoord" for an eventual change in SIMA.
