Use a class to check validity of withDictwip/withdict
This moves handling of the magic 'withDict' function from the desugarer
to the typechecker. Details in Note [withDict].
I've extracted a part of T16646Fail to a separate file T16646Fail2,
because the new error in 'reify' hides the errors from 'f' and 'g'.
WithDict now works with casts, this fixes #21328.
Part of #19915
