Some of the Intel platforms have odd numbers of LUT entries and we
need to tests a couple of values around the expected result. Bring
back the CRC equal function we need that doesn't trigger an assert
right away, while we still assert if we can't find a correct result in
the outter loop.
v2: update Fixes field (Jani)
v3: Use memcmp (Ville)
v4: missing signed-off

This was intentionally left out of the abi since CRC have fairly low
entropy and can't be reliably compared for inequality in testcases.
Spotted while fixing up warnigns in docs, but given that igt_assert_crc_equal
has a big comment explaining why only the positive assert exists I'm not
sure all those docs are all that useful :(

When testing multple outputs, make sure to set the gamma values before
testing the output. Otherwise we're testing using the gamma values
that were reset after last output was tested. Without this, the first
output passes, but each output after that will fail.

The GAMMA_LUT/DEGAMMA_LUT/CTM properties must be updated when the
legacy ioctl is triggered to ensure the new properties do not impact
older userspace code.
v2: Add checks verifying the content of CTM & DEGAMMA_LUT properties

This test enables testing of :
* degamma LUTs
* csc matrix
* gamma LUTs
* legacy gamma LUTs
v2: turn assert into require to skip on platform not supporting color
management
v3: add invalid blob ids tests
v4: Try to match CRC results against several values around the
expected result for platforms with odd LUT items
v5: Fix running tests with multiple screens
