MessageHeader is not a standard SOAP element (that would be Envelope or Header) and therefore Salesforce won't be able to read it or send it to your Apex method.

You could route your web service calls through an API Gateway or similar middleware that understands MessageHeader. The middleware may be able to translate your payload to standard SOAP header(s) or include them in a body of a SOAP message. Mulesoft is a Salesforce product that can do this.
