drm/amd/display: Add support for HF-VSIF

[Why]
- Currently there is no support for HF-VSIF
- The current support of VSIF is limited to H14b infoframe

[How]
- refactor VSIF
- Added new builder for HF-VSIF
- Added the HF-VSIF packet to DisplayTarget
- Updates DC to apply HF-VSIF updates when updating streams
