All these tests call `self.get_stdout()` which returns `None` despite the program printing output as expected:
```
C:\Users\tcwg\llvm-worker\lldb-aarch64-windows\build>C:\Users\tcwg\llvm-worker\lldb-aarch64-windows\build\lldb-test-build.noindex\tools\lldb-dap\launch\TestDAP_launch.test_default\a.out
arg[0] = "C:\Users\tcwg\llvm-worker\lldb-aarch64-windows\build\lldb-test-build.noindex\tools\lldb-dap\launch\TestDAP_launch.test_default\a.out"
env[0] = "ALLUSERSPROFILE=C:\ProgramData"
<...>
cwd = "C:\Users\tcwg\llvm-worker\lldb-aarch64-windows\build"
```
I notice that all other tests using `self.get_stdout()` in other files have been skipped on Windows too.
