drm/amd/display: Add AVI infoframe copy in copy_stream_update_to_stream

[ Upstream commit c8bedab2d9a1a0daa49ac20f9928a943f7205582 ]

[WHY]
Ensure AVI infoframe updates from stream updates are applied to the active
stream so OS overrides are not lost.

[HOW]
Copy avi_infopacket to stream when valid flag is set.
Follow existing infopacket copy pattern and perform a basic validity check before assignment.
