Build FMS as Shared?

[mathomp4]

Recently FMS 2024.03 was released. In that is a change requested by @srherbener (issue: NOAA-GFDL/FMS#1558, PR: NOAA-GFDL/FMS#1559) to allow for shared library builds of FMS.

I suppose the question is: what should GEOS use? We use FMS in...weird ways. We do our wacky link with r8 but allow r4 thing for MOM vs FV3. I know from testing that the r4/r8 override that should work for us does not (not enough is overridden).

I'll do some testing and probably ping @tclune to see what we should do depending on the outcome.

Have we ever opened specific issues with FMS for the interfaces that we see as not being supported?

Maybe long ago with our old FMS, but I should do it again with modern FMS. I'll try it out next week.
