Make Wasm workload sizes more uniform

Such that each single iteration takes at least 20ms (to not be too noisy), but not too long (such that we can run as many iterations as possible in under 2s Wall time).
Concretely, this means:
- Reducing work per iteration for tsf-wasm and richards-wasm and sqlite3-wasm, while at the same time increasing number of iterations for those three.
- Reducing HashSet-wasm iterations to 50 (it was the only Wasm line item to run >4s Wall time, and there is already plenty precedent for 50 iterations).
