Make bookmark app shortcuts target chrome_proxy.exe on Windows

This CL updates the bookmark app shortcut creation code to target
chrome_proxy.exe instead of chrome.exe. chrome_proxy.exe just opens
chrome.exe with all arguments forwarded and is behaviourally equivalent.

The primary difference is chrome_proxy.exe isn't associated with the
chrome.VisualElementsManifest.xml file. This fixes a bug where pinned
bookmark app shortcuts all use the Chrome logo instead of their own.
