Use the same real kind for axis variables in restart files as real kind used for data variables.

[DusanJovic-NOAA]

Description

This PR updates io routines to use the same data type (float or double) for axes in restart files as data type used for data variables. This will make a temporary fix in restart write routine in the write grid component unnecessary and make everything consistent and restart files written by FMS and write grid component will be identical.

Testing

How were these changes tested? Yes
What compilers / HPCs was it tested with? Intel and GNU on Hera
Are the changes covered by regression tests? Yes
Have the ufs-weather-model regression test been run? On what platform?

• Will the code updates change regression test baseline? Yes, all tests that write restart files will need new baselines
• Please commit the regression test log files in your ufs-weather-model branch
