Implement Lazy BrowserWindow Initialization

App launching using electron-efl was faster than xwalk and
used more memory because of webview creation under window init.
Now BrowserWindow will not initialized when wrt-loader preloads.
This decrease the memory consumption of wrt-loader and
app launching time is nearly the same as the xwalk.
