Add entry points for interacting with Go

Browse Source 
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.
