Support SpecialFolder UserApplicationDataDir for internalLogFile when parsing nlog.config

[snakefoot]

Trying to resolve #4861

Introduces support for these symbol-types (both for internalLogFile and normal layouts):

• ${commonApplicationDataDir} - C:\ProgramData
• ${userApplicationDataDir} - C:\Users\%USERNAME%\AppData\Roaming
• ${userLocalApplicationDataDir} - C:\Users\%USERNAME%\AppData\Local

Those are long names, but I think those are the best options and it's consistent. So LGTM :)

PS I'm on holiday with limited internet connection.

Maybe we should document the layout renderer with dashes on https://nlog-project.org/config/?tab=layout-renderers ?

Think it will be confusing with the very simple layout-support for internalLogFile-option.

Decided that ApplicationDataDir was too generic. One might think it would be the directory of the running application. Created #4868

Can the internal-logging wiki be updated to specify where the locations re what was posted above? but also for linux, i cant find what these resolve to in linux online

${commonApplicationDataDir} - C:\ProgramData
${userApplicationDataDir} - C:\Users%USERNAME%\AppData\Roaming
${userLocalApplicationDataDir} - C:\Users%USERNAME%\AppData\Local

SpecialFolders on Linux is platform dependent. But maybe this page can help: https://github.com/NLog/NLog/wiki/Special-Folder-Layout-Renderer https://learn.microsoft.com/en-us/dotnet/api/system.environment.specialfolder
