[dev.typeparams] internal/buildcfg: enable defer/go wrapping everywhere
For register ABI, we wrap deferred/go'd function with arguments or results in an argumentless closure, so the runtime can call the function without knowing how to marshal the arguments, or reserving frame for arguments and results. The wrapping mechanism works everywhere, regardless of whether the register ABI is used. And wrapping will simplify the compiler and runtime's implementation for defer and go calls. For example, the compiler will not need to marshal arguments for defer/go calls, the opendefer metadata will not need to contain argument information, and _defer record will be fixed-sized. Enable wrapping everywhere.
