drm/amd/display: Update VSC HDR infoPacket on TF change

Browse Source 
[why]
OnSetSourceContentAttribute it does not trigger an update for the VSC
with TF change.

[how]
In this call, create a new VSC infoPacket based on the new config, and
allow DisplayTarget decide if an update and pursuant passive flip is
necessary
