Finish conversion from bloom filter to prefix set in safe browsing.

Finish conversion from bloom filter to prefix set in safe browsing.

Always use the prefix set, delete any old bloom filter.  Users who
haven't launched since M-22 (so more than six weeks) will run without
protection until first update.

In M-23 SB2.FilterLoad records which filter was loaded at startup.  PREFIX_SET
is at 98.7% on beta channel, making a little progress each day, I expect it to
be around 99.5% or better by the time M-23 goes to stable.

Of the leftovers, it's likely:
 - people who seldom run Chrome
 - people who quit before first safe-browsing update
 - people who's profile is messed up

I can't think of a strong reason to bump this another release cycle for any of
those cases.
