- [lldb][windows] print an error if python.dll is not in the DLL search path llvm/llvm-project#164893
… path (llvm#164893) This is a follow up to llvm#162509. Using the `SearchPathW` API, we can ensure that the correct version of Python is installed before `liblldb` is loaded (and `python.dll` subsequently). If it's not, we try to add it to the search path with the methods introduced in llvm#162509. If that fails or if that method is `#ifdef`'d out, we print an error which will appear before lldb crashes due to the missing dll. Before llvm#162509, when invoked from Powershell, lldb would silently crash (no error message/crash report). After llvm#162509, it crashes without any indications that the root cause is the missing python.dll. With this patch, we print the error before crashing.
