[GPU Porting] MOM_tracer_flow_control.F90

[edoyango]

access-om3:

• call_tracer_set_forcing (0.11s)
• call_tracer_surface_state (0.07s)
  • claude says this call goes to esmf (for access-om3) which handle the mpi stuff. Could mean that this stuff ought to stay on CPU?
• call_tracer_column_fns (0.06s)
  • in OM3 it seems to only call convert_MLD_to_ML_thickness [GPU Porting] MOM_interface_heights.F90 marshallward/MOM6#65 but there could be some array copies that need to be ported?
• call_tracer_flux_init (0.04s)
• call_tracer_stocks (0.02s)
• tracer_flow_control_init (0.02s)
