Add entry points for interacting with Go A "ffi_go_closure" is intended to be compatible with the function descriptors used by Go, and ffi_call_go sets up the static chain parameter for calling a Go function. The entry points are disabled when a backend has not been updated, much like we do for "normal" closures.
