This CL creates a new class AutofillHelper that factors out the autofill related code out of render_view.cc.

This is to limit the bloating of RenderView code, which would soon get even worse once we move the Webkit autofill to Chrome.
There is no logic change in this CL.

BUG=None
TEST=Make sure form autofill and autocomplete work as expected.
