Revert of Safe numeric library: base/numerics (copied from Chromium) (patchset #11 id:250001 of https://codereview.webrtc.org/1753293002/ )

Reason for revert:
Looks like the Chrome iOS build is broken because of these two changes.  So I'm going to have to revert.  Here's the error:

Original issue's description:
> Safe numeric library added: base/numerics (copied from Chromium)
>
> This copies the contents (unittest excluded) of base/numerics in
> chromium to base/numerics in webrtc. Files added:
> - safe_conversions.h
> - safe_conversions_impl.h
> - safe_math.h
> - safe_math_impl.h
>
> A really old version of safe_conversions[_impl].h previously existed in
> base/, this has been deleted and sources using it have been updated
> to include the new base/numerics/safe_converions.h.
>
> This CL also adds a DEPS file to webrtc/base.
