Use LoggerMessage for logging in ActorContext

[woksin]

Description

Start introducing LoggerMessage slowly by using it in ActorContext. Refering to this issue #1651 where we talked about introducing it and to see how it would look. I use it in some projects and IMO I think it provides good readability, seperation of concerns at the same time of improving performance :)

Weird with these failing tests as they should not really be affected by these changes :)
