Subject: [PATCH] Apply include-cleaner to api direct files (2/2).

This is a follow up for https://webrtc-review.googlesource.com/c/src/+/360680.

* Adding some missing <optional> include.
* Adding a IWYU pragma to force keeping an include.

Note that I've added the CQ bot 'iwyu_verifier' to ensure the repo stays clean. It is still work in progress and it currently needs to be triggered manually.
FYI I used these command line to run iwyu:
> for i in api/*.cc; do ./tools_webrtc/iwyu/apply-include-cleaner $i; done
> for i in api/*.h; do ./tools_webrtc/iwyu/apply-include-cleaner $i; done
