We should centralize all of the Chrome-specific crashpad_handler setup stuff in
one location. The other thing that we now do is call
SetupFallbackCrashHandling(). That happens in
chrome/app/chrome_exe_main_win.cc’s wWinMain(), should it also happen here?

I felt it was clearer to have the
SetupFallbackCrashHandling/RunFallbackCrashHandler incantations in the same
scope, but I'm happy to move the setup if you feel strongly about it.
