clean up of wallace tree generation in booth multiplier #4421

Open andyfox-rushc opened 1 month ago

Improve multiplier performance by reducing partial product summation to parallel wallace tree See function ReduceBitsParallel.

(Martin, I have marked this as a draft pull request, I am still digging into cleaning up the multiplier & wanted to have a visible thread for the improvements).
