For #10555 - Use INPUT_HANDLING_UNKNOWN as the default of InputResult…

…Detail

We need to wait until having a response from GeckoView on how it handled the
touch only after which we'll know whether to animate the toolbar or not.

The edgecase scenario of having pull to refresh enabled even before having a
response from GeckoView will still work because "canOverscrollTop()" only
checks for the touch to not be handled by the browser to pan the page.

* 🌟️ New `AdsTelemetry` based on a web extension that identify whether there are ads in search results of particular providers for which a (Component.FEATURE_SEARCH to SERP_SHOWN_WITH_ADDS) Fact will be emitted and whether an ad was clicked for which a (Component.FEATURE_SEARCH to SERP_ADD_CLICKED) Fact will be emitted if the `AdsTelemetryMiddleware` is set for `BrowserStore`.
* 🌟️ New `InContentTelemetry` based on a web extension that identify follow-on and organic web searches for which a (Component.FEATURE_SEARCH to IN_CONTENT_SEARCH) Fact will be emitted.
