Looking at [StepOutRequestHandler](https://github.com/llvm/llvm-project/blob/main/lldb/tools/lldb-dap/Handler/StepOutRequestHandler.cpp) it doesn't check `arguments.singleThread` so all threads will run even when a DAP client sends `singleThread=true`.

Makes more sense to land that first before we say we support `singleThreadExecution`
