This might be a bad idea, especially on the webidl side. However, we started talking about the idea that modelines are a lint error (https://github.com/servo/servo/issues/10719), and these changes would be required before enabling a modeline lint.
If it bitrots, it's easy to recreate with
```
find * -type f -exec sed '/- Mode:/d' -i {} +
find * -type f -exec sed '/ vim:/d' -i {} +
git checkout -- python/tidy/servo_tidy/tidy.py
git checkout -- python/tidy/servo_tidy_tests/spec.webidl
git commit -a
```

This is a series of already-reviewed changes by @yodalee from #5025, rebased onto current servo master, with some fixups applied:
* Fixed build errors/warnings from the latest rust upgrade.
* Marked `tests/wpt/web-platform-tests/encoding/single-byte-decoder.html` as expecting CRASH.
I could not verify locally that the new test annotation is correct, since the test appears to hang rather than crash on my Linux box. (Or maybe I just didn't wait long enough.) If this crash isn't consistent, or if it takes a long time, maybe we should skip this test instead?
