bootstrap: propagate test-args to miri and clippy test suites

For Miri I verified this works. For clippy, unfortunately it doesn't seem to work as a stage 0 tool:
```
./x.py --stage 0 test src/tools/clippy --test-args init
```
gives
```

But propagating `--test-args` to the test suite seems to make sense regardless.

Use `dyn` trait syntax in more comments and docs

Probably missed it out during earlier dyn refactoring.

Use sort_unstable_by in its own docs

Currently it uses `sort_by` instead of itself.
