Windows QPA: Fix some clang-tidy-warnings

- Replace index-based loops by range-based for
- Change else if to if after return/break/continue or simplify
- Fix indentation
- Do not check for non-null before invoking delete on pointer
- Use isEmpty() instead size() to check for empty containers
- Remove C-style casts
- Use raw string literal
- Do not repeat type in return, use {} instead
- Reference local variables by const ref where applicable
