[Intel-gfx] [PATCH i-g-t v3 2/4] tests/ chamelium: Remove the frame dump tests

[Lyude Paul]

NAK. You're right that these don't actually give us any advantage over
just using CRCs and are just slower, however I left these tests in here
moreso just so we had something to actually test the frame dumping
functions so that we could avoid regressing them by accident since
we're the only users of those functions right now.

If I recall properly, isn't there a list of tests in igt's source that
they use for determining which tests to run on the CI? I think a better
solution would be to just disable this for CI runs, and maybe add some
comments pointing out that this test is only really useful for
developers making changes to the chamelium library.
