Rebuild apidsl'd headers in cmake.

- Moved apidsl headers next to their generated versions. In the future,
  perhaps all (or most) headers will be apidsl-generated, so the sources
  should stay together.
- Try to find apidsl/apigen binary and astyle binary and use it for the
  format test. Don't run the format test if these can't be found.
