Purpose of changes:

- HB diffusion in CAM6/7 performs mixing for stable conditions (Ri>0) as well as background mixing in addition to unstable mixing (Ri<0)
Modify HB in CAM6/7 to only mix for unstable conditions
- add div4 sponge (in SE dycore) in MT configuration for stability
- friction frictional heating in del4 sponge


Closes issue https://github.com/ESCOMP/CAM/issues/1062
Expect answer changes for all CAM7 regression tests and SE dycore tests

One-line Summary: Corrected L93 default IC files

One-line Summary: HB mods + dycore mods
Github PR URL: https://github.com/ESCOMP/CAM/pull/1071

Purpose of changes (include the issue number and title text for each relevant GitHub issue):
- Possible modification to HB in CAM7: https://github.com/ESCOMP/CAM/issues/1062
- HB diffusion in CAM6/7 performs mixing for stable conditions (Ri>0) as well as background mixing in addition to unstable
mixing (Ri<0)
- Modify HB in CAM6/7 to only mix for unstable conditions
- add div4 sponge (in SE dycore) in MT configuration for stability
- friction frictional heating in del4 sponge

The L93 hybrid coefficients had a discontinuous kink, or offset, creating an anomalously thin layer
in the 300 hPa - 100 hPa altitude range. This region overlaps with the L58 grid, but for some reason
the L58 grid didn't get contaminated like it was in L93. We aren't sure how this happened.
More here: https://github.com/ESCOMP/CAM/issues/1034
