AndroidX Webkit: add loud interstitials in testapp

No change to production, just testapp. This implements support for Loud
(big, red) interstitials in our demo app, by pointing the WebView at the
main page of the test site.

This is mostly a copy of the standalone Safe Browsing test app.

Bug: 124773936
Test: Manual - working as intended
Change-Id: I4825f3a57581a9af01b32ea3c5c6f8073cb6c8ab

+ * red (or grey) error page with considerable description when it's "full" sized (takes up almost
+ * the entire available device screen), and we believe it's likely the predominant part of the UI.
+ * <p>
+ * This {@link android.app.Activity} points to a safe page, but that page itself has links to
+ * (fake) malicious resources of various threat types, to allow testing each threat type. Within the
+ * interstitial, the user can click any of several links which provide more information about Safe
+ * Browsing overall, including "proceed" and "back to safety" buttons for navigation.
