Add ApiScan to nightly build (#8605)

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 the nightly build and test run.  This
task should help us identify related issues earlier, rather than having
to wait for a full scan of VS.  The task can take a long time to execute
so it has been added to the nightly job rather than the PR or CI jobs.
