Don't std::move() trivally-copyable type; it makes no difference

Browse Source 
CodeChecker says:

 std::move of the variable 'parts' of the trivially-copyable type 'QCalendar::YearMonthDay' has no effect; remove std::move()

So don't bother with the move, and remove && from the signature of the
function being called in all four places. Assert that the type *is*
trivially copyable.
