Fix Safari-side SafeBrowsing telemetry

• Component: New Bugs
• Status: RESOLVED FIXED

[Eliot Hsu]

Telemetry for Safari Safe Browsing was previously handled in Safari. Now that WebKit decides whether or not to show Safe Browsing warnings, and queries the Safe Browsing Service itself, we should pass along the (anonymized and privacy-preserving) telemetry to Safari to fix the metrics that were previously there.

If navigatesFrame is true, then we know that result is ContinueUnsafeLoad::Yes.  This check seems unnecessary.

And this seems unreachable.

In the case where the Safe Browsing warning page shows, and the user clicks on the "Learn more..." or "report an error" links instead of "Visit this unsafe website", then `navigatesFrame` and `forMainFrameNavigation` are both true, but `continueUnsafeLoad` is `ContinueUnsafeLoad::No`.
