Revert of Move make_scoped_ptr into //base/memory/ptr_util.h. (patchset #2 id:20001 of https://codereview.chromium.org/1838323002/ )

Reason for revert:
No longer needed given the updated migration plan.

Original issue's description:
> Move make_scoped_ptr into //base/memory/ptr_util.h.
>
> Preparatory CL for renaming scoped_ptr to std::unique_ptr. One of the
> changes is replacing all uses of make_scoped_ptr() with WrapUnique(),
> which lives in a separate header.
>
> In order to incrementally update files to use the new header, this CL
> moves make_scoped_ptr to ptr_util.h but still includes it in
> scoped_ptr.h to avoid breaking the build during the transition.
