Fix ice water FV3 increment variable name and add a few more (#1112)

This PR corrects the name of ice water mixing ratio in the corresponding
fields metadata YAML and adds a few more tracers. Many these additional
tracers may never have increments, but I might as well add them just in
case. (I got these tracers by putting a print statement in the UFS code
when I was debugging my cubed-sphere increment reading branch)
