POP configure script should separate marbl_cppdefs from cppdefs

[mnlevy1981]

It will be useful to separate which variables in POP's configure script are needed by POP vs which will be moving to MARBL when MARBL's build system matures.

A good starting point would be something like

   # this will determine if need to rebuild at runtime - force user to call $CASE.buildexe

maybe adding marbl_ to the local variables that are MARBL specific as well. Also, we can compute ECOSYS_NT and CISO_NT from the PFT counts...

  # Compute tracer counts!
  # Each zooplankton class adds:
  # -- one new tracer (C) to the base tracer module
  # -- As of now, zoo13C and zoo14C are hardcoded in the ciso tracer module
  # Each autotroph class adds:
  # -- three new tracers (Chl, C, Fe) to the base tracer module
  # -- two new tracers (C13, C14) to the ciso tracer module
  # Each autotroph class that is a silicifier also adds:
  # -- an additional tracer (Si) to the base tracer module
  # Each autotroph class that is a calcifier also adds:
  # -- an additional tracer (CaCO3) to the base tracer module
  # -- two new tracers (Ca13CO3, Ca14CO3) to the ciso tracer module
  $ECOSYS_NT       = 15 + $ZOOPLANKTON_CNT + 3*$AUTOTROPH_CNT + $SILICIFIER_CNT + $CALCIFIER_CNT;
  $CISO_NT         = 6 + 2*$AUTOTROPH_CNT + 2*$CALCIFIER_CNT;

Closing this as MARBL no longer has any cppdefs (everything is runtime configurable as of #189)
