refactor: add most of src/util to iwyu

fanquake · fanquake · commit 07f2c25d04c3 · 2022-07-08T11:06:01.000+01:00
These files change infrequently, and not much header shuffling is required.

We don't add everything in src/util/ yet, because IWYU makes some
dubious suggestions, which I'm going to follow up with upstream.
