I assume the plan will be to eventually remove the
CONFIG_MEMCPY_SLOW_KUNIT_TEST option and just rely on the "speed"
attribute to filter these out. That has the disadvantage that the
tests will still be built, but is probably the nicer long-term
solution.
I suppose we could remove it in this patch, too, but I suspect it
makes more sense to have a deprecation period to make sure the
attributes are working well. That being said, maybe add a note to the
CONFIG_MEMCPY_SLOW_KUNIT_TEST help text to advertise this?
