Is your feature request related to a problem? Please describe.

We have to evaluate performance for #10799.

Describe the solution you'd like

This issue can be closed with nvbench compare result run on upstream device segmented sort vs graph capturable device segmented sort from #10799 on B200 and 6000 Pro.

    nvbench compare of upstream (f32edf2c69) v the implementation #10799

    B200 RTX 6000 Pro
    median +0.83% +1.66%
    time-weighted suite total +3.91% +1.48%
    >1% faster / >1% slower 115 / 185 64 / 223
    within +-1% 99 112

    The regressions concentrate in the same two bands on both devices:

    1. Micro calls: millions of near empty segments at the smallest data size. I think it is because of per claim latency with no work to over it.
    2. Power law inputs with a few large segments: might have something to do with how work is claimed (some CTAs can get two big segments at once)
