[Intel-gfx] [PATCH i-g-t] kms_cursor_crc: Add a subtest with a 256x256 gradient cursor

Some of the kms_cursor_crc subtests where failing on Geminilake. The root cause was an error on programming the pre-CSC gamma tables, which led to small rounding errors that, although not sufficient to change the image as captured at 8bpc with the Chamelium, were enough to generate a different CRC.
