Password bubble: Confirm blacklisting a site if passwords exist.

If a user blacklists a site with existing saved passwords, those
passwords will be deleted. In order to ensure that a user doesn't
accidentally lose data, we prompt them to inform them of the risk, and
ask for confirmation of the decision.

Vaclav, would you mind taking an initial pass over this CL while I clean up some
of the visual mess and add tests?

Thanks!

LGTM.
+1 for this improvement; I was bitten in the past, when I refused to save my
Chrome sign-in account password and deleted my @chromium.org password by doing
that.

Cheers,
Vaclav

NOTRYing. Flaky win_chromium_rel tests are killing me.
