Add utgw and vtgw to variable output

[ma595]

Enables utgw and vtgw variable output.

Passes lchnk to gw_nlgw_dp_ml(state1,ptend,lchnk) as I was getting "block out of bounds" errors with ncol passed to outfld function.

This PR registers UTGW_NL and VTGW_NL in gw_nlgw_dp_init routine using addfld, and then outputs tendencies using outfld. The following changes need to be made to user_nl_cam:

nhtfrq=0,-24
mfilt=1,1400

fincl2 = 'U:I','V:I','T:I','UTGW_NL:I','VTGW_NL:I'

I believe 'I' corresponds to instantaneous and 'A' to time averaged. Care has to be taken to register the output variables properly. This is something I need to experiment with properly.

IMPORTANT: Then make sure to run ./preview_namelists.

NOTES: I tried with ncol and pcols passed to outfld and this led to the block error.

And atm_in reports that UTGW and VTGW is properly registered.

TODO before merging:

• Remove pcols experimentation.
• Neaten
