Add flexible controls of GPU configuration and remove old GPU configuration

[sjsprecious]

This PR:

• updates the configurations for the GPU offload based on the new XML variables in CMEPS (https://github.com/ESCOMP/CMEPS/pull/363).
• removes the old approaches for GPU configurations.
• updates the module versions and batch script template on Derecho.
• removes #PBS -V option as it incorrectly populate the NGPUS env variable from the login node to the compute node on Derecho.

@jedwards4b will issue a separate PR to introduce these changes.

I updated the nvhpc compiler version to 23.5 with a newer version of ESMF8.6.0b03. The GPU run finished successfully on Derecho.
