[logging, debugger] remove unescesary logic and only query USER env variable once (#2800)

- censoring an username would lead to the variable being queried everytime something is written, just store it on a static
- dont use a map<> for something that can be done in a switch statment (and that the compiler will optimise for free!!!)
