Use FormatUrl in Android PageInfoPopup

This adds a new UrlFormatter.formatUrlForDisplayWithNormalEscaping()
function, and uses it in the Android PageInfoPopup to make its URL
display correctly de-punycode URLs that are safe to convert back to
Unicode for display.

This also adds url_formatter unittests for the specific usage of
FormatUrl that the new function uses under a variety of URL
conditions.
