Delete outdated forms replaced by lead-form

With the new way of doing forms in the CLS the only form widget that works is the lead-form, so we are removing the old form widgets.  Before this is deployed we will need to update the following sites once we get the ok from Product.

They will need the current widget garden master updated on the and the lead forms swapped out. Then we can merge this branch and deploy to everyone and not orphan widgets in the CMSes.
