Move the `WeightHelpers` to its only client
Move the WeightHelpers
to its only client.
This MR:
- just moves the code, but does not delete anything
- will result in TruthUtils being a header-only library
- prevent the overlinkage of the
WeightHelpers
code into hundreds of packages where it is not used. - commented out the WeightHelpers test
