Summary: Step 1 in removing the dependency on ReactContext from GuardedRunnable and other related classes. These are extensively by native modules and view managers, so in order to remove the bridge dependency from those modules we'll need to first decouple these classes from ReactContext. It turns out they only need ReactContext for its handleException method, which delegates out to product code. For backwards compatibility I'm exposing another NativeModuleExceptionManager in ReactContext that simply wraps its handleException method (since this interface already does everything we need). I figured I'd keep around an extra constructor that still uses ReactContext for now instead of trying to migrate everything over at once.
