By default, turn off volcanic forcings when configure option "-chem none" is used with cam6 physics.

Change aerosol names in the physics property files of prescribed stratospheric aerosols so the the 3 modes have unique names and there are no namespace issues with history fields added in ndrop_bam if the user chooses to turn on the volcanic forcings.

The default configuration with "-chem none" is to have no volcanic forcings. One can turn on the cam6 volcanic forcings by setting prescribed_strataero_feedback=.true.

Added an aux_cam test since it seems that there is a desire to support this configuration.

Refactor how WACCM physics QBO nudging is turned on.

Remove reprosum settings from FSD prealpha test.

Closes #169
Closes #261
Closes #334
