tidy: Remove redundant casting. (qt5/qt6)

This test "detects explicit type casting operations that involve the same source and destination types, and subsequently recommend their removal". These changes were made for qt5 by the clang-tidy program. They were then adjusted manually so that they didn't break qt6 compilation. https://clang.llvm.org/extra/clang-tidy/checks/readability/redundant-casting.html
