  [WebAssembly] Fold any/alltrue SIMD boolean reductions with eqz (#184704)

Existing ISel patterns match setne/seteq following SIMD boolean reductions
any_true and all_true, and drop the ones that are redundant (because the
reductions always return 1 or 0). This adds patterns to also produce eqz
instructions instead of a comparison with a const.
