Add support for sRGB inverse EOTF

Unit testing this in VKMS shows that passing 0 into
this function returns -1, which is highly counter-
intuitive. Fix it by checking whether the input is
>= 0 instead of > 0.

CTM values are defined as signed-magnitude values. Add
a helper that converts from CTM signed-magnitude fixed
point value to the twos-complement value used by
drm_fixed.

We'll construct color pipelines out of drm_colorop by
chaining them via the NEXT pointer. NEXT will point to
the next drm_colorop in the pipeline, or by 0 if we're
at the end of the pipeline.
v3:
- Add next pointer to colorop to be used by drivers
and in DRM core

This aligns with most other DRM drivers and will allow
us to add new VKMS config options without polluting
the DRM Kconfig.
v3:
- Change SPDX to GPL-2.0-only to match DRM KConfig

Debugging LUT math is much easier when we can unit test
it. Add kunit functionality to VKMS and add tests for
- get_lut_index
- lerp_u16

- Use include way of testing static functions (Arthur)

s are in signed-magnitude fixed
point, whereas the drm_fixed.h implementation uses 2s-complement.
The latter one is the one that we want for easy addition and
subtraction, so we convert all entries to 2s-complement.

A whole slew of tests for CTM handling that greatly helped in
debugging the CTM code. The extent of tests might seem a bit
silly but they're fast and might someday help save someone
else's day when debugging this.
