add run time information in NUOPC cap

[jiandewang]

this mini PR added some run time information in NUOPC cap for us to monitor the UFS running speed. A logic variable "write_runtimelog" is added here with default value of False. As usual I am asking MOM6 major users for the review although only NCAR may use this feature (and we asked @alperaltuntas and @marshallward for a pre-review before this formal PR). Thanks for your very helpful suggestions.

Changes are in the NUOPC driver that is not used in GEOS application.

[marshallward]

I am approving this, but I would like to repeat my concern about using MPI_Wtime in this driver. The function can become blocking if certain flags are set, which will block across the entire MPI_COMM_WORLD, not just MOM6. If other ranks are not calling MPI_Wtime, then the model will hang.

We recognize that your groups are maintaining the NUOPC cap, so I won't let this concern hold up the patch. But if a future NUOPC user encounters problems with this, then we may want to revisit this change.

[abozec]

We don't use the NUOPC cap in our applications, so it won't affect us.

[kshedstrom]

This code doesn't affect me either.

thanks for everybody's time and effect, I am going to merge it
