fix(mobile): rotate android raw natively instead of createBitmap

the exif rotate now happens in a small native pass (lock pixels + a
tiled copy straight into the output buffer) so there's no second full
bitmap. about 6x faster on big raws. also fixes orientation 5/7 which
were swapped, and forces argb_8888 so high-bit-depth dng don't
under-allocate. keeps the skia path as a fallback for odd formats.
