Gary Russell f4a17886be INT-4272: Read Only Header Improvements ...

JIRA: https://jira.spring.io/browse/INT-4272

- Honor read only header configuration when building from an unchanged message
- Support adding read only headers to the message builder factory

* Move `IntegrationMessageHeaderAccessor.containsReadOnly()` to the
`MessageBuilder` to avoid confusing

**Cherry-pick to 4.3.x**
