Add context argument to ObjectCodec.{serialize,deserialize}

Context implementations are currently empty, just doing the plumbing in this
change. Once this is in we can start passing along the ObjectCodecRegistry, which
will allow runtime codec resolution for classes not known at compile time.
We'll also inevitably add some memoization helpers, allowing us to optimize the
serialization process further.
