encoding/jsonpb: add unmarshal option to ignore unknown fields

This feature seems to be used quite a bit, and the conformance tests
treat this as required, perhaps as a "required option" since the
developer guide states:

"Proto3 JSON parser should reject unknown fields by default but may
provide an option to ignore unknown fields in parsing."

Also, all invalid UTF-8 errors in skipped values are also returned as it
is similar to a parse error, except it is a non-fatal one.
