Move HTTP-Bad to Feature API and implement new options

This CL moves the HTTP-Bad from outdated field trial groups to the Feature API
with parameters to control the UI treatment. It adds three new UI treatments for
nonsecure  pages:

- mark all nonsecure pages as Not Secure
- mark all nonsecure pages as Not Secure and treat them as actively dangerous when
  a form field is edited
- mark all nonsecure pages as Not Secure and treat them as actively dangerous for
  passwords and credit card fields

This doesn't implement any DevTools or Page Info changes for these configurations.
