refactor(netcdf): updates focused on flopy parity

[mjreno]

Adjustment to model NetCDF input file creation that align with FloPy #2417:

• Fix DIS mesh_face_x array, which was off by an index
• Rotate mesh x and y coordinates when angle of rotation has been specified
• change global attributes "modflow6_grid" and "modflow6_model" to "modflow_grid" and "modflow_model", as these identifiers might be more generally applied
• After FloPy PR is merged, a follow up PR will update autotests to use new functionality
