BufferAttribute.setArray method chaining

[takahirox]

Let's return this from BufferAttribute.setArray() and make it chain-able as other methods of BufferAttribute do.

Fine. How about returning this for InterleavedBuffer.setArray(), too?

And, of course, update the docs. :-)

Regarding this as a return value, @donmccurdy had a suggestion: see #13816 (comment).

Agreed. I was just missing InterleavedBuffer.setArray() and documents. About method:this in the doc, let's consider in another PR.

BTW, I wanna and am gonna enable "method chaining", not only for loaders or attributes, but also for other modules. For example I found bunch of methods in Object3D and BufferGeometry that should be chain-able but are not yet.
