[Autofill] Add a notion of "verified" profiles.

Each Autofill profile and credit card is now associated with an origin.  For
automatically aggregated profiles, this is the domain they were aggregated from.
For manually entered profiles, this is something more like
"chrome://settings/autofill".  Profiles with unknown origin have an empty string
as their origin.

A profile is considered to be "verified" if its origin is a non-empty,
non-web-URL string.  When a user makes an edit to a profile via
chrome://settings/autofill, it becomes verified.  (If the user simply views the
profile, but does not make any changes, it is not upgraded to verified status.)

Once a profile is in the verified state, nothing can knock it back into the
unverified state.  The only way to add variants to a verified profile is to
enter them directly via Chrome's settings UI.  Any automatically aggregated
profiles that would be merged to a verified profile are simply discarded, since
we don't want to mess up profiles that users have directly edited, nor do we
want to pollute the global namespace of profiles.  We could instead keep track
of verified/unverified state per variant, but this adds a relatively large
amount of code complexity for relatively little gain.

This CL is just the first part of the work.  Follow-up CLs will:
  (1) Extend the WebDB to be origin-aware.
  (2) Extend Sync to be origin-aware (requires a Sync backend change).
  (3a) Write the origin to the WebDB.
  (3b) Ensure that web origins are cleared from the WebDB when users select to
       erase history.
  (4) Ensure that all clients of the PersonalDataManager are setting the origin
      correctly for any profiles they add.
