Constructs a string view from the temporary string str. This function returns a QStringView16 which is only valid for the lifetime of str.

If the string view is passed to another function, verify that the called function does not attempt to save a copy of the view. As per the C++ standard, accessing a view after the lifetime of the temporary string has expired, is undefined behavior.
