cmd/protoc-gen-go: centralize presence and lazy logic into filedesc

With this change, the generator and runtime use the same logic
to decide whether a presence bitmap entry is necessary,
instead of two (possibly diverging) copies of the logic.

I have verified Google-internally that sharing the logic
yields exactly the same results as the old logic on all our .protos
(see Google-internal CL 755276656 for details).
