Reland "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.

Original CL: https://codereview.chromium.org/1028563003/
Reason for reland: Linux ChromiumOS GN (dbg) build broke (missing qcms dep in
ash/BUILD.gn)

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.

Hi folks this a reland of the CL you previously reviewed with just a change to
ash/BUILD.gn to try and fix the following build:

https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%...

Unfortunately this doesn't seem to be covered by any trybots.

Thanks for your time.

In my experience after a revert such as this people generally reopen the old
issue and upload a new patchset to that. That way we can see the patchset delta,
and unchanged parts are already approved.
