Standardize logging locations across desktop platforms (#6238)

* Standardize logging locations across desktop platforms

* Return null instead of empty literal on exceptions

* Remove LogDirectoryPath from LoggerModule

* Catch exception when creating DirectoryInfo in FileLogTarget

* Remove redundant log path vars, handle exception better, add null check

* Address styling issues

* Remove extra newline, quote file path in log, move directory check to OpenHelper

* Add GetOrCreateLogsDir to get/create log directory during runtime

* misc format changes

* Update src/Ryujinx.Common/Configuration/AppDataManager.cs
