Manages tracing of WebViews.

Remarks
Manages tracing of WebViews. In particular provides functionality for the app to enable/disable tracing of parts of code and to collect tracing data. This is useful for profiling performance issues, debugging and memory usage analysis in production and real life scenarios.
The resulting trace data is sent back as a byte sequence in json format. This file can be loaded in "chrome://tracing" for further analysis.
Example usage:
TracingController tracingController = TracingController.getInstance();
tracingController.start(new TracingConfig.Builder()
.addCategories(TracingConfig.CATEGORIES_WEB_DEVELOPER).build());
...
tracingController.stop(new FileOutputStream("trace.json"),
Executors.newSingleThreadExecutor());
