The engine was using a global to store a timestamp representing the launch of the engine. This timestamp is initialized with a JNI call on Android and during shell setup on other platforms. Later the timestamp is added to a FlutterEngineMainEnter timeline event used to measure engine startup time in benchmarks. This PR removes the global and the JNI call and moves the timestamp into the settings object.
