Overall, cleaning up remaining lit uses. #2851 had removed FileCheck invocations from some of the explorer tests; this starts as just restoring that. But, now that we have far fewer `lit` tests, it seems best to refine `lit.cfg.py` to focus on providing fewer commands (not all were even used). Also, adding testing of an error to explorer (which I noticed due to a change that would've broken that) made me notice that autoupdate_lit_test's for_lit logic didn't actually work, so I'm just cutting it and going to manual updates. Really, we might want to just remove lit autoupdate support altogether since it's only a couple tests using it, but I'm not ready to make that change right now. Fixes #2912
