drm/amd/display: Send HDMI VRR metadata in VTEM info packet slot

[Why]
Brief blank on HDMI each time VRR engaged and disengaged, with no modeset
at either transition.

amdgpu_dm_update_freesync_state_on_stream() built the VTEM on top of the
buffer holding the AMD FreeSync SPD payload, which becomes
stream->vrr_infopacket. DC routes that to HDMI generic slot 3 (SPD) and
vtem_infopacket to slot 6 (VTEM), and vtem_infopacket was never populated.
So slot 3 carried a VTEM payload the sink parsed as an SPD
InfoFrame, no VTEM was sent, and v_total varied with no valid metadata
describing it. DP uses the VSC/AS-SDP path and is unaffected.

[How]
Build the VTEM into a separate vtem_infopacket, gated on the sink not
advertising AMD FreeSync. Track it in dm_crtc_state, include it in the
freesync_vrr_info_changed comparison and the reset path, and pass it
through bundle->stream_update.vtem_infopacket.
