- Added AddExtension, RemoveExtension and GetExtensions methods body

- Added a ChromeExtensionInfo class, that mimic the returned JS values from GetExtensions method (see https://electronjs.org/docs/api/browser-window#browserwindowgetextensions)
- GetExtensions return a Dictionary<string, ChromeExtensionInfo>, to respect JS documentation declaration.
