Use an assembly wrapper to call EnumDisplayMonitors callback

I suspect (with very little supporting evidence) that the issue is that the
games are passing a non-stdcall callback function to EnumDisplayMonitors(). 
That results in the stack being messed up after it returns.

It's similar to the issue fixed by
<https://source.winehq.org/git/wine.git/?a=commit;h=b08c400fe2924bf7137e350c3673b11d3a6378c2>
and the fix will probably be similar.  I've attached a patch based on that. 
Give it a try.


Another thing to try: test with the X11 driver.  That would presumably require
a similar patch.  Set the following registry setting:

[HKEY_CURRENT_USER\Software\Wine\Drivers]
"Graphics"="x11,mac"

You will also need to make sure that Wine will find the X11 libraries at load
time.  That may entail setting the DYLD_FALLBACK_LIBRARY_PATH environment
variable which is complicated by El Capitan's System Integrity Protection
(SIP).  Ask if you encounter trouble.
