This patch add or removes XFAIL decorator from various tests which were marked
xfail for windows.
since 44363f2 various tests have started passing but introduced a couple of new failures.
Weight is in favor of new XPasses and I have removed XFail decorator from them. Also
some new tests have started failing for which we need to file separate bugs. I have
marked them xfail for now and will add the bug id after investigating the issue.
