Add telemetry to keep track of how often we perform query parameter stripping per navigation.

[Emma Zühlcke [:emz]]

Bug 1706616 already added a basic telemetry probe to keep track of how many times we perform query stripping for navigations and redirects. In this bug we're looking to extend our telemetry for query param stripping to answer the following questions:

• If we strip, what's the distribution of amount of query parameters stripped? Minimum, maximum, average? How many other (non classified) query parameters are there?
• Out of the query params on our strip-list, which ones get stripped the most?
