This implements the persistence timer and the logic to write measurements to a persistence file off-the-main thread using JSONWriter. The code to load persisted measurements off the disk uses the builtin JSON parsing functions from JS (as we cannot use jsoncpp). It additionally exposes the ClearProbes method to clear the probe storage and trigger clearing the persisted data (GeckoView only). MozReview-Commit-ID: 94FoZac47Cw
