Update submodules for ABI compatability

[hellkite500]

Given #834 , we need to ensure the ngen submodules supported and automatically built are compatible with the current BMI ABI. It looks like SLOTH and bmi-cxx were updated as part of the process, but these were not and need to get updated.

• SoilMoistureProfiles
• CFE*

*CFE may need some additional consideration, especially given the v1.0.0 release tag. This change may need to be back ported on a bugfix branch and a v1.0.1 release added to ensure this commit carries into v1. Or we drop support for v1 and only support v2 after that commit?

@PhilMiller is the change from macro to const int in the C interface problematic with the updates on ngen? Based on my reviews and understanding, I don't think it is, but I could be wrong. If it isn't an issue in our current usage, then the previous comment can likely be safely ignored for the time being.

The change to CFE's bmi.h for macros vs const int affects the CI for other formulation modules that integrate CFE as part of their testing (i.e. they say #include "bmi_cfe.h" \ #include "bmi.hxx"), but shouldn't affect ngen itself, since we never compile the different modules together.
