- move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
  from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
  + initialise them in pkg/mom_common/mom_init_fixed.F
- store in common block (in MOM_VISC.h): useHarmonicVisc, useBiharmonicVisc
  & useVariableVisc, (previously local flag harmonic, biharmonic
  & useVariableViscosity, were set for each k in mom_common/mom_calc_visc.F)
