Use new NIF api for yielding

[lpgauth]

Hi,
Erlang 17.3 introduced a new way for NIFs to yield back to the scheduler. I'm not sure how easy it would be to integrate this into the NIF generator.

Here's an example project using the new API:

It would probably be fully doable somehow. I haven't yet had a very close look at the changes in 17.3, but generally, I think it is probably fully doable in some way or another.

Hi, I did a quick attempt at it on the branch nif-on-dirty-scheduler if you would like to try it out. It might perhaps not work on 17.0 (or other pre-17.3 versions).

Hi, I've merged the nif-on-dirty-scheduler branch into master 3.15.0, it should use a dirty cpu-bound scheduler if there is support (17.3 configured with --enable-dirty-schedulers)
