v2.6.6: Fix for ifx

This release has fixes for the Intel ifx compiler when running with Ops emissions. This patch was already in develop (i.e., v2.7.0) but was backported here.

This is zero-diff for intel ifort and only affects ifx

---

Fixed

• Fixed ifx compilation errors in legacy GOCART GridComps (Ops emissions path):
  • Changed intent(in) to intent(inout) on w_c (Chem_Bundle) arguments in Aero, CFC, CH4, CO, CO2, and Rn GridComps, as sub-components temporarily modify registry indices
• Additional fixes in CO_GridCompMod.F90:
  • Initialize eCO_bioburn_ to 0.0 to prevent use of uninitialized data when diurnal_bb is false
  • Guard DEALLOCATE of ier with an ALLOCATED check
  • Add local ios variable in CO_Emission to prevent host-association aliasing under optimization
