Remove NPAPI support for form data

Since PPAPI doesn't support it either, remove (some of) the corresponding blink
code.

dcheng: please review.

sigbjorn: FYI, from the logs it looks like you touched the form interaction
last. Because HTMLObjectElement::appendToFormData is a noop now, I suspect
HTMLObjectElement doesn't need to be a FormAssociatedElement any more - but I'm
way out of my depth here.

(I think you're right about FormAssociatedElement, but let's do that in a
separate CL)

OK, maybe not: the spec defines some of this behavior, so even though it's a
no-op, we'll probably have to leave it.
