Add CMake config to support building shared libraries

[srherbener]

Description

This PR adds CMake configuration to optionally build shared libraries. Building static libraries remains the default action.

Fixes #1558

How Has This Been Tested?

I tested these changes on my Mac laptop. I verified that static libraries build by default and by using the cmake command line option -DSHARED_LIBS that shared libraries were build instead.

JEDI is currently using FMS 2023.04 and I tested these changes (relative to the 2023.04 version of CMakeLists.txt) and verified that FV3-GFS built successfully with either static or shared FMS libraries, and indeed the issue with the static libraries is fixed by using shared libraries instead.
