[igt-dev] [PATCH i-g-t v4 1/4] lib/igt_chamelium Added chamelium_frame_match_or_dumpn which returns bool that the captured frame matches with reference framebuffer

[Kunal Joshi <kunal1.joshi@intel.com>]

Added chamelium_frame_match_or_dump which returns bool that the captured
frame matches with reference framebuffer.

(v2)
        Removed previously added function chamelium_assert_frame_dump_eq.

(v3)
        No change.

(v4)
        Removed duplicate function code chamelium_assert_frame_dump_match
