Jon Ross-Perkins 70c94cb5b4 Clean up --no-prelude-import uses (#5722) 
For some of these, it's just replacing with min_prelude/none.carbon.
Some had min_preludes specified, and I'm generally switching those to
none.carbon as well. The one exception is the destroy.carbon test, which
I noticed because of #5678
