Oleksandr Pavlyk 149a2d257a Allow timing-only bulk data to confirm SAME ...

Permit nvbench-compare to use bulk timing samples to confirm SAME even when
sample frequency sidecars are unavailable. This lets legacy --jsonbin outputs,
which recorded sample times but not frequencies, avoid AMBG results when
summary noise is high but timing coverage clearly supports equality.

Cycle coverage is still required when frequency samples are present, and
FAST/SLOW clear-gap confirmation remains cycle-based.

Add regression coverage for noisy bulk samples that exceed the SAME noise
ceiling but are classified SAME from bulk timing/cycle coverage, including the
timing-only legacy-data path.
