Subject: [PATCH] iwyu: Do not export C++ headers in most cases

`IWYU pragma: export` enforces the transitive inclusion of the headers,
which undermines the purpose of IWYU.

The remained cases seem useful and could be considered separately:
- `<cassert>` in `util/check.h`
- `<filesystem>` in `util/fs.h`
- `<chrono>` in `util/time.h`
