Add AgX tonemapper option to Environment

Browse source 
Technical implementation notes:

- Moved linearization step to before the outset matrix is applied and
  changed polynomial contrast curve approximation.
  - This does *not* implement Blender's chroma rotation to address hue shift.
    This hue rotation was found to have a significant performance impact.
- Improved performance by combining the AgX outset matrix with the Rec 2020 matrix.
