feat(engine): make benchmark inputs deterministic

[hoank101]

Towards #13535

Changes state root task and channel perf benches to use the deterministic proptest runner

[Rjected]

Edited the PR description because it doesn't actually close the original issue, just modifies a few benches (there are more). Also edited it to be more descriptive - would highly appreciate similar quality descriptions in the future!

just one nit, otherwise this looks good to me
