Refactor cpu_features_wrapper.h functions from C to C++.

Browse Source 
As mentioned on https://webrtc-review.googlesource.com/c/src/+/183380,
then relanded as https://webrtc-review.googlesource.com/c/src/+/183444,
functions in cpu_features_wrapper.h should be refactored to use
C++ features like namespaces and drop the WebRtc_ prefix.
