Tuple: Rename Tuples.of(Object...) to Tuples.ofArray(Object...)

[Pyknic]

Since Object[] inherits Object, it means that Tuples.of(Object) has the same signature as Tuples.of(Object[]). This causes problems since a method that returns a single Object can't be used with Tuple.of() without it wrapping the result in an array of dimension 1.

Example:

Object foo() {
    return ...;
}

...

Tuple t = Tuples.of(foo()); // This will resolve to Tuples.of(Object[]), not Tuples.of(Object).

I suggest to rename the static constructor method to Tuples.ofArray(). This issue also affects TupleOfNullable.of()

We could check List.of() functions and see how that is handled in Java 9.

This will affect the API
