OutputDebugString messages while debugging

[cristianadam]

At No output in "Application Output" with debugger we can see that lldb has an issue with qDebug() calls whilst debugging in Qt Creator.

This only happens with the Desktop Qt 6.8.2 llvm-mingw 64-bit (lldb) kit. The Desktop Qt 6.8.2 MinGW 64-bit (gdb) and Desktop Qt 6.8.2 MSVC2022 64bit (cdb) kits work as expected.

I've managed to find a workaround, but I think it would be great if lldb would work on Windows like the other debuggers.

I've found https://reviews.llvm.org/D128541 which I think is an attempt to fix this issue, but it remained as a work in progress 😢
