Fix boundaries setting for "SampleBufferVideoRenderer" re-layouting (#…

…506)

Hello @hiroshihorie! 
I'm experiencing issues with the camera's front-to-back switch feature,
which occasionally causes the video frame to be incorrectly oriented in
landscape mode when it should be in portrait mode.

To resolve this issue, I've found that it's essential to update the
frame of the **AVSampleBufferDisplayLayer** after applying the
transformation matrix. This is because the transformation matrix also
rotates the frame, which can result in incorrect orientation if the
frame is not updated accordingly.
