[ISSUE #9302] SendMessageContext add message type

[ymwneu]

Which Issue(s) This PR Fixes

Fixes #9302

Brief Description

Currently, when setting msgType in SendMessageContext, only normal messages and ordered messages are distinguished. Transactional messages and delayed messages are not differentiated.
In subsequent implementations of the send message hook, it won't be possible to differentiate the actual message type.
