Provide function equivalent API for UMA macros in histogram_macros.h

Project Member Reported by nikunjb@chromium.org, Sep 26 2016

Issue description

histogram_macros.h provide macros for addition histogram. They are very efficient, but doesn't cover all use cases, like
If histogram name is generated at runtime, special care has to be taken when using macro so that generated code behaves as expected. It is not possible in some cases.

Provide a equivalent API for using UMA macros have similar functionality exposed as functions.

Please use functions defined in base/metrics/histogram_functions.h instead of using base::Histogram::FactoryGet directly.
