Update to ESMA_cmake v3.38.0

[mathomp4]

This PR updates GEOSgcm to ESMA_cmake v3.38.0. This is a fairly trivial update for GEOS with updates mainly for non-usual builds of GEOSgcm. Updates include fixes for the NAG and ifx compilers, adding FindESMF.cmake for use with Spack builds of GEOSgcm, and adding support for Hygon processors.
