This provides a means to explicitly specify the return type of an OpaqueClosure, which previously was not possible without calling `jl_new_opaque_closure` directly. As a result, `@opaque AT (...)->...` is no longer an allowed form to define an OpaqueClosure. Instead `@opaque AT->_ (...)->...` should be used.

This gives users a way to explicitly specify the return type of an OpaqueClosure, and it also removes the old syntax
@opaque AT ...in preference of@opaque AT->_ ...
