P0646R1 for Debug mode

[François Dumont]

Right after I hit the send button I realized that I had forgotten to 
remove the definition of __cpp_lib_list_remove_return_type on the Debug 
forward_list side.

I haven't plan to define this macro in this context, I prefer to leave 
it to normal implementation.

So here is the updated patch.
