Oilpan: Disallow tracing Raw/Ref/OwnPtr fields.

We want to completely disallow tracing off-heap fields since tracing of such fields can not be correctly identified by conservative stack scanning. This CL disallows tracing off-heap smart-pointers and raw pointers. We still allow tracing of off-heap collections since the on-heap versions don't yet support backings with vtables.
