This changes the BodyBuilder to create FunctionTypeParameter instead
of FormalParameterBuilder for "parameters" in function types. This
avoids the creation of unnecessary VariableDeclaration nodes
function types.
The types of these VariableDeclarations where created before the type
variable scope was completed, introducing an artificial dependency on
the pending nullability computation.
