pw_rpc: Update for protocol changes

- Update to handle STREAM_END and CANCEL packet semantics.
- Detect and handle packet decoding errors.
- Send ERROR packets when a malformed or unexpected packet is received.
- Switch from uint32 to fixed32 for service and method IDs. fixed32
  stores evenly distributed uint32s (like hashes) more efficiently than
  uint32.
- Use a void return type for server streaming RPCs, since the status is
  sent from the ServerWriter.
- Move response sending from the Server to the Method. Previously, the
  server always sent a response. However, only unary RPCs should send an
  immediate response. This structure also gives the Method class more
  control over the semantics for RPCs.
