[ci] Add API Scan job (#225)

Context: https://devdiv.visualstudio.com/DevDiv/_wiki/wikis/DevDiv.wiki/25351/APIScan-step-by-step-guide-to-setting-up-a-Pipeline

The ApiScan task has been added to pipeline runs against `main`.  This
task should help us identify related issues earlier, rather than having
to wait for a full scan of VS.
