Description

Provide a detailed description of what this PR does.

This PR updates history and restart write netcdf routines to support writing multi tile native grid (cubed sphere) files. Currently, native grid history files are written by ESMF field bundle prototype routine, which is still available (I did not remove it from the write grid component) but is disabled by USE_ESMF_IO cpp macro by default.
When cubed sphere grid outputs are selected the number of io tasks per write group must be divisible by 6 (for global configurations).

Is a change of answers expected from this PR? No.
