drm/amd/display: add plane shaper LUT and TF driver-specific properties

On AMD HW, 3D LUT always assumes a preceding shaper 1D LUT used for
delinearizing and/or normalizing the color space before applying a 3D
LUT. Add pre-defined transfer function to enable delinearizing content
with or without shaper LUT, where AMD color module calculates the
resulted shaper curve. We apply an inverse EOTF to go from linear
values to encoded values. If we are already in a non-linear space and/or
don't need to normalize values, we can bypass shaper LUT with a linear
transfer function that is also the default TF value.

There is no shaper ROM. When setting shaper TF (!= Identity) and LUT at
the same time, the color module will combine the pre-defined TF and the
custom LUT values into the LUT that's actually programmed.

v2:
- squash commits for shaper LUT and shaper TF
- define inverse EOTF as supported shaper TFs

v3:
- spell out TF+LUT behavior in the commit and comments (Harry)
- replace BT709 EOTF by inv OETF

v5:
- get shaper blob correctly (Joshua)
