Add Maui FileSystem LayoutRenderer

[snakefoot]

Cache directory (Returns the LocalCacheFolder directory)

FileSystem.Current.CacheDirectory;

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalCache/

App data directory (Returns the LocalFolder directory that is backed up to the cloud)

FileSystem.Current.AppDataDirectory;

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalState/

For NetStandard (and others) then it can just return:

System.AppContext.BaseDirectory

Notice MAUI performs virtualization so when resolving SpecialFolder.LocalApplicationData then it automatically redirect to custom folder:

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalCache/
