Add switch to change capture rates and remove overwriting parameters in initialCap

[fschreyer]

Purpose of this PR

Add switch to change capture rates of technologies with carbon capture. Also stop overwriting pm_emifac in initialCap to actually apply these changes in policy runs.

@robertpietzcker : To finally fully avoid these issues in the future, I'd like to stop overwriting more of the parameters. Some of them do not need initialCap results. What about moving the pm_eta_conv adaptions and vm_deltaCap fixings out of initialCap, too?

  Execute_Loadpoint 'input_ref' pm_eta_conv = pm_eta_conv;
  Execute_Loadpoint 'input_ref' o_INI_DirProdSeTe = o_INI_DirProdSeTe;
  Execute_Loadpoint 'input_ref' pm_EN_demand_from_initialcap2 = pm_EN_demand_from_initialcap2;
  Execute_Loadpoint 'input_ref' pm_pedem_res = pm_pedem_res;
  Execute_Loadpoint 'input_ref' pm_dataeta = pm_dataeta;
  Execute_Loadpoint 'input_ref' pm_aux_capLowerLimit = pm_aux_capLowerLimit;
  Execute_Loadpoint 'input_ref' vm_deltaCap.l = vm_deltaCap.l;
  Execute_Loadpoint 'input_ref' vm_deltaCap.lo = vm_deltaCap.lo;
  Execute_Loadpoint 'input_ref' vm_deltaCap.up = vm_deltaCap.up;
