internal/impl: change unmarshal func return to unmarshalOptions

The fast-path unmarshal funcs return the number of bytes consumed.

Change these functions to return an unmarshalOutput struct instead, to
make it easier to add to the results. This is groundwork for allowing
the fast-path unmarshaler to indicate when the unmarshaled message is
known to be initialized.
