Convert Lookalike URL throttle to use WillStartRequest.

This CL modifies the lookalike URL throttle to block requests before
they happen, rather than after they commit (but before Chrome processes
their response). This keeps logic cleaner (e.g. by not needing to worry
about remembering redirect chains across refreshed requests) at the
expense of possibly showing two interstitials in a row if the URL would
have triggered a different interstitial (as in invalid hostnames).
