This migrates explorer tests to file_test, using the new --autoupdate functionality. Per discussion, the trace tests that were using "not" output are mostly migrated to checking full output. The main exception is tests that were including trace output from the prelude: the prelude output is pretty long (multiple MB already) and I think it wasn't the intent to include, only trace output from the small program. This is the remaining use of lit support, so the supporting libraries are also removed here.
