pw_rpc: Python client improvements

- Use the Call object directly as the context object. This is simpler
  and makes cancelling prior calls easier.
- Return the previous context when a duplicate RPC is called.
- Cancel the prior RPC call when the same RPC is called again on the
  same channel.
- Update the response iteration API.
  - Don't use "block" since it is redundant with timeout_s=0.
  - Accept optional "count" arg for how many responses to receive.
  - Don't cancel the RPC if iteration fails. If there is a server error,
    the RPC will be terminated anyway. The user may cancel directly on
    the call object or by using it in a with block.
  - Remove accidental get_responses on client streaming RPCs.
- Propagate exceptions from user callbacks so they aren't just logged.
- Add unit and integration tests.
