Revert of Load and apply a vcgt table from an ICC file to the internal display (patchset #15 id:300001 of https://codereview.chromium.org/1028563003/)

Reason for revert:
breaks compilation

https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20GN%20(dbg)/builds/1084

Original issue's description:
> Load and apply a vcgt table from an ICC file to the internal display
>
> When the command line switch --internal-display-color-profile-file is provided
> load the given ICC file using qcms and extract the VCGT data. Use this VCGT
> data to apply a gamma ramp to change the output on the internal display using
> drmModeCrtcSetGammaRamp.
>
> BUG=471749
> TEST=On a link_freon device add the command line option to load a sample ICC
> file (e.g. Bluish.icc to give a blue tint) and observe on startup that the
> internal display is blue tinted.
>
