[AF] Move links to addresses and payment methods to main Settings page

This CL eliminates the "Autofill and payments" page and move "Addresses
and more" and "Payment methods" into the main Settings page.

A follow-up CL will fix allow access to the "Payment methods" page even
if the corresponding toggle is enabled by policy, to allow users to
access payment apps.
