Hook up chrome.exe manifest in the Windows GN build.

Hook up chrome.exe manifest in the Windows GN build.

This generates a proper version manifest for chrome.exe and also for the version assembly.

This adds a new way to get the chrome version info programatically at GN time. Although this adds another exec_script call, it removes four such calls in remoting so there is a net speed increase.
