[lldb][Windows] XFAIL TestExitDuringStep.py on ARM64 (#228392) This is a follow up to https://github.com/llvm/llvm-project/pull/227318 which re-enabled `TestExitDuringStep.py` on Windows. Those tests still fail on ARM64 Windows (see https://github.com/llvm/llvm-project/pull/228391). XFAIL them for now. GitOrigin-RevId: ba680de5049dbd0238d9e023ac60fcdf1e09fb48
