dzn/ci: Update WARP, remove stale fails/flakes, and add more tests

The updated WARP fixes nearly a dozen bugs across clip distance interpolation, details of sampler addressing order-of-operations, integer sampler behaviors, non-normalized sampler behaviors, txs for invalid mip levels, early-z stencil fail, primitive ID in VS -> FS pipelines, and a couple others. This should be enough for CI to reflect an eventual 99.75% pass rate in the VK1.0 CTS once the rest of the Dozen changes land.

There's one small fix in here for !20400 (merged) (the wrong version of a patch landed 😞) and then a couple CI expectations updates, removing tests that just haven't been running (either due to .toml excludes or fraction) or haven't been flaking.
