Collect compat data for APIs guarded by IsolatedContext

Looks like some new APIs are guarded by https://github.com/WICG/isolated-web-apps:

- https://wicg.github.io/direct-sockets/ 
- https://wicg.github.io/web-smart-card/ 

In order for the collector to be able to test for support, we ought to meet the requirements for IsolatedContext (looks like it wants strict CSP among other things).
