Remove dependency on autofill_core_browser from policy_component.

Remove dependency on autofill_core_browser from policy_component.

policy_component doesn't need to depend on autofill_core_browser. Also
added dependency on gfx_geometry in favicon_base. policy_component was
failing to compile without it.
