Relocate password leak toggle from safe browsing page to privacy page

This change removes the password leak detection toggle from the
standard protection fragment and makes it it's own setting on the
privacy page for Android. We are also removing the safebrowsing
protection level dependency on the password leak toggle enable status so
the now the user has free choice to select whether they want the
password leak toggle enabled regardless of safe browsing status.

We will also remove the enhanced protection bullet point about
password leak detection since that is no longer accurate.
