Add information on the gridcell 2D index on ouput

With #2995 I'll have the ability to output the 2D gridcell index. This could be reported on a fail with the error checking, or could be stored as part of the decomposition information at startup.

Definition of done:
- [x] Add the i, j index to the write_point_context subroutine in abortutils
- [ ] Add it to the BalanceCheck and CNBalanceCheckMod fails
- [ ] Add it to error index reporting in lnd_import_export_utils.F90
- [ ] Add it to index reporting fails in subgridAveMod
- [ ] Add it to index reporting fails in initInterpMindist.F90
- [ ] Add it to the following miscellansous places:
- [ ] DustEmis*.f90
- [ ] UrbanFluxesMod
- [ ] ch4Mod
- [ ] HillslopeHydrologyMod
- [ ] Check for other occurances with something like:
-- `git grep write | grep "index"`
-- git grep 'write(iulog' | grep "grc%lon"
