Cleanup across E2EE code

Notably:
- simplified unnecessarily verbose constructs;
- formally aligned (no re-numeration was necessary)
  QOlmMessage::Type with corresponding OLM_ constants;
- dropped QOlmSession::encryptMessageType() because it's very
  sensitive to the order of calling with QOlmSession::encrypt()
  (and encrypt() itself already calls it and returns the message
  type);
- simplify the return type of pickle() calls that can only fail due to
  an internal error;
- replace const QString& with QStringView or const QByteArray&
  where appropriate;
- use '\0' where it was meant to be instead of '0'.
