This unifies `dump-tokens` and `dump-parse-tree` so that we don't keep writing basically the same code repeatedly. I'll need to modify the output of SemanticsIR::Print more, and may soon unify printing multiple IRs this way (particularly including the builtins SemanticsIR) but this is intended to offer a starting point. I may eventually try to unify lit.cfg.py files, but I was thinking about whether that works in various contexts we may run in and eventually decided copying the driver/testdata/lit.cfg.py file would be the easiest solution.
