build, win: use target_arch to link with node.lib

Using `target_arch` in addon.gypi to link against Node.js library. This
variable was written into build/config.gypi on the `configure` stage.

Do not copy node.lib into node_root_dir/Release or node_root_dir/Debug
on Windows, link it from node_root_dir/target_arch directory.
