Simulator's "Clear Site Data" button is potentially misleading #291
Description
The button is labeled Clear Site Data (compared to the other button, Forget Site), but both buttons end up invoking the "clear browsing history for attribution" algorithm, not the algorithm associated with the Clear-Site-Data header, which is currently not exposed in the UI at all.
We should expose all 3 operations in the UI with a checkbox for determining the value of the forgetVisits parameter, e.g.
[`Clear-Site-Data`] as site [site.example]
[Clear data as user] for [site.example (empty = all sites)] [x] Forget Visits
