Add Chrome tracing for callChromeHiddenMethod
Extensions tend to spend a lot of their time in JavaScript invoked from here. This change is to help see that time is being spend in javascript in chrome://tracing.
This is related to crbug.com/112892 which tracks the fact that the extension system calling directly into V8 here also misses a bunch of other instrumentation we normally get when entering JavaScript.
