Update spectral-element WACCM regression test

### What is the feature/what would you like to discuss?

SMS_Ln9.ne30pg3_ne30pg3_mg17.FW2000climo.derecho_intel.cam-outfrq9s_rrtmgp test uses 70 layer WACCM (so CESM2 setting). Should be updated to CESM3. Perhaps we can start by replacing this test with Mijeong's 2 degree setup: ne16pg3

I am changing hyperviscoity settings and we are fixing the sponge layer (in physics) bug which both are needed for WACCM spectral-elements. Before we proceed though: Has the vertical resolution for WACCM been set in stone yet?

### Is there anyone in particular you want to be part of this conversation?

@fvitt @mijeong135 @mbramberger

### Will this change (regression test) answers?

Yes

### Will you be implementing this enhancement yourself?

No
