Add chrome_proxy.exe target on Windows

This change adds a new executable to Windows called chrome_proxy.exe which
opens chrome.exe with all arguments forwarded.

In a future patch bookmark app shortcuts will be updated to point to
chrome_proxy.exe instead of chrome.exe so they don't pick up the
chrome.VisualElementsManifest.xml file when pinned to the Windows 10
start menu. This fixes a bug where pinned bookmark app shortcuts all
use the Chrome logo instead of their own.
