Introduce the iOS consumer API.

The purpose of this API is to make the iOS port less vulnerable to bustage
during merges while in the process of upstreaming (see
https://sites.google.com/a/chromium.org/dev/developers/design-documents/layered-components-technical-approach).

+This directory exists to allow iOS code that is not yet upstreamed to call
+Chromium code without being vulnerable to breakage during a merge.
+Specifically, not-yet-upstreamed code is allowed to use the interfaces
+provided in public/. Any change to one of these interfaces should get a full
+review from an OWNER, as such a change will require corresponding changes to
+code not yet upstreamed. Any change to code not under public/ can be TBR'd to
+an OWNER.
