[LLDB] Add/Remove xfail for some API tests on Windows

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.
