loopyt b4f7a42652 test(h20): compare two hosts' Triton builds, not just two backends on one host
`h20_ops_ab.py` assumed the TileLang backend is importable, so on a vendor image it could
not start at all -- which is exactly where the Triton backend needs checking. Two modes fix
that:

* `--dump DIR` saves the selected backend's output per case.
* `--compare DIR` checks against dumps written elsewhere.

Together they answer "do triton 3.5.1 and 3.7.1 agree" without either host having TileLang.
Case builders that genuinely need a package the host lacks now report a skip instead of
aborting the run, so partial coverage is visible rather than fatal; the import of the
sampler's C++-backed inputs moved into the one builder that uses it for the same reason.

This is what showed the 19 ported kernels produce element-wise identical output across
triton 3.5.1, 3.6.0 and 3.7.1 -- 115 cases, no differences.
