Refactor HasXFAField into HasFormInfo

The existing API is too restrictive for collection the metrics
information that we want. Specifically it only tells us if there are
XFA forms in the document, but not AcroForms. This refactoring makes
the method more general, so that non-XFA information is provided
also. This change in semantics of the return value required some
changes at the call sites of the API.
