Utils: Replace Result class by type alias to std::expected<T, QString>

... to be able to conveniently return also non-void cases without being
exposed to the syntax of expected.

The price for the more general approach is some uglification of the
void case: The previous 'Result' is now equivalent to 'Result<>',
which needs to be spelled out in function signatures, and some
changes to the special cases.
