  -----------
  [libc++] Implement LWG3549: view_interface need not inherit from view_base

Implement LWG3549 by making `view_interface` not inherit from `view_base`. Types
are still views if they have a public and unambiguous derivation from
`view_interface`, so adjust the `enable_view` machinery as such to account for
that.
