For gen11+ platforms, there are frequent crc mismatch issues observed
in color tests. This is happening due to hardware limitation
(pipe rounding). One of the solutions to fix this is by rewriting
color tests and making them compatible with chamelium.

In this patch series, color tests are modified to have frame dump
comparison instead of crc comparison using chamelium hooks. This
will be useful even for future platforms. Also, with this approach
we could enable limited-range subtest which was commented in kms_color
because of crc mismatch.

  lib/igt_chamelium: add function to compare two frame dumps.
  tests/kms_color_chamelium: add subtests to validate color.
