Maybe fix Coroutine.wrap?

Fix #3687

[SquidDev]

I think this needs to handle the case where the coroutine returns multiple values. I think if you use table.pack, you can get something closer to what PUC Lua does:

    local result_pack = table.pack(coroutine.resume(thread, ...))
    if not result_pack[1] then error(result_pack[2], 2) end
    return table.unpack(result_pack, 2, result_pack.n)

This looks like a restoration of the past implementation.
Why did they change it to this? It's really strange.

Do you consider submitting a PR? I'm not good at Lua. I'm worried about new problems.
