Reviewed by Brady Eidson.

We want to observe when sites in the field exceed various key memory footprint thresholds (e.g. 2GB,
4GB, etc.). To do this, we let the embedder specify those thresholds in _WKProcessPoolConfiguration.
We also add a _WKWebsiteDataStore delegate method that is called when WebContent's footprint exceeds
those thresholds.

Theis notification only works on the Mac, since they require the use of the periodic memory monitor
(which is only enabled on Mac).
