Group known trackers in the tracking content UI

[kbrosnan]

What is the user problem or growth opportunity you want to see solved?

As a user I would like to understand the companies that are tracking web usage. Being displayed the raw list of domains that are trackers is not easy to understand. As an example compare the list of trackers shown on https://abcnews.go.com on Android vs Desktop.

It would be nice if we could show entities rather than tracking origins by default. We could do this on both desktop and mobile. We can get the entity-list from Disconnect. There should still be a way to look at the origins if needed though.
