Provide overload for std::byte for QIODevice read/write operations

Since Qt 6.2 C+17 is required. Since std::byte exists as of C+17, there is a better type than
char for operations at byte level. Therefore it would be nice if the read/write methods of QIODevice and any inheriting classes could also provide an overload for std::byte (SonarLint currently criticizes reinterpret_cast<char*>).
