[LLDB] XFail on Windows TestThreadAPI.py test_StepInstruction

TestThreadAPI.py test_StepInstruction started failing after llvm#97493

Following assertion fails but I am not sure if test will pass after
changing the test.

AssertionError: 'void __cdecl call_me(bool)' != 'call_me(bool)'

I have marked it as xfail I ll run it on a Windows machine to find
an appropriate fix.
