Extract plottable counter from perf results logger.

Split out of https://webrtc-review.googlesource.com/c/src/+/165389.

I disentangled the plottable counter printer from the perf result
printer so it will work for both future implementations of the perf
test JSON writers. The only thing plottable counters and the
results writer had in common was that both wrote JSON anyway.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
