claincly f69a2f5131 Render PQ to DebugSurface in transformer.
For HLG input in transformer, FinalWrapper is configured to only output HLG to
encoder. But since DebugPreview is configured to take PQ for HDR content, the
color will not look correct.

This CL allows overriding the MatrixTP output transfer function, so
that FinalWrapper can output

- HLG to encoder
- PQ to debug preview
