[ANativeWindow] Apply remaining API feedback
* move ANativeWindow_getFrameId to a platform api, as
native_window_get_frame_timestamps is not stable and therefore the
associated api surface is not complete enough to be stable.
* Adjust documentation for returned errors. In most cases errors aren't
returned in practice. In the case of ANativeWindow_setDequeueTimeout the
errors are enumerated explicitly.
