[Lldb-commits] [lldb] [lldb][Windows] Skip assert frame recognizer tests on Windows (PR #224602)

[Charles Zablit via lldb-commits]

https://github.com/charles-zablit created https://github.com/llvm/llvm-project/pull/224602

https://github.com/llvm/llvm-project/pull/224269 introduced the assert frame recognizers on Windows. This caused a regression on the Windows ARM64 build bot: `PECallFrameInfo` does not handle ARM64 yet.

This patch skips the test on arm64 Windows.

Tracking issue: https://github.com/llvm/llvm-project/issues/224600
