Changes variables named data to other variable names

[mcallic2]

Description
data was introduced as a "data statement" in fortran 77. It can be used to declare/assign values to variables.
In FMS, the instance of data being used as a variable name happens often. This PR suggests changes to these variable names, and does not include any directories/modules that are either no longer used and/or deprecated (i.e. axis_utils, mpp_io, fms_io, etc).

Fixes # 1328

How Has This Been Tested?
autotools with gcc/13.1.0, netcdf/4.9.2, mpich/4.1.2, hdf5/1.14.1-2, libyaml/0.2.5
