We've previously only included the accuracy tests on platforms that
claim to be accurate. Can we rephrase the goal of the test such that it
sounds more like a universal truth that should also be valid for the
sampling backends? "The busyness should never exceed 100% (within a
margin of error)..." And since accuracy is currently protected by
has_busy_stats, let's try to find a different name.

CI Bug Log - changes from IGT_6004_full -> IGTPW_5512_full
====================================================
Summary
-------
**FAILURE**
Serious unknown changes coming with IGTPW_5512_full absolutely need to be
verified manually.
If you think the reported changes have nothing to do with the changes
introduced in IGTPW_5512_full, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.

So assert(igt_hweight(flags & (TEST_TRAILING_IDLE | TEST_LONG)) <= 1); ?

Yeah.. At least I know the oddity is related to sampling. Since even on
