Constructs a new any object.
1) Constructs an empty object.
2-3) Copies (2) or moves (3) content of
other into a new instance, so that any content is equivalent in both type and value to other, or empty if other is empty.4) Constructs an object with initial content equivalent in both type and value to
value.5-8) Equivalent to the preceding constructors except that the stored value is constructed using the supplied allocator instance.
