This CL adds a reverse JNI call to our Android Native Activity that
sets the orientation of the screen based on width and height.
To achieve this we:
* Attach to the java thread once at the beginning to grab JNI env.
* Detach from the thread once when platform sends APP_CMD_DESTROY
* Set the orientation during test init
