Dana Jansens bcba76aca7 Require file tests to specify a min-prelude (#5818) 
Use `full.carbon` min-prelude for any tests using the full prelude. A
few tests were using it unnecessarily and are changed to a more minimal
one in the process.

Any test which does not include some min-prelude will now fail with an
error.
