Make config filename changable for releases & Log to Ryujinx directory if application directory is not writable (#4707)

* Remove GetBaseApplicationDirectory() & Move logs directory to user base path

We should assume the application directory might be write-protected.

* Use Ryujinx.sh in Ryujinx.desktop

This desktop file isn't really used right now,
so this changes effectively nothing.

* Use properties in ReleaseInformation.cs and add ConfigName property

* Configure config filename in Github workflows

* Add a separate config step for macOS

Because they use BSD sed instead of GNU sed

* Keep log directory at the old location for dev environments

* Add FileSystemUtils since Directory.Move() doesn't work across filesystems

Steal CopyDirectory code from https://learn.microsoft.com/en-us/dotnet/standard/io/how-to-copy-directories

* Fix "Open Logs folder" button pointing to the wrong directory

* Add execute permissions to Ryujinx.sh

* Fix missing newlines

* AppDataManager: Use FileSystemUtils.MoveDirectory()

* Make dotnet format happy

* Add a fallback for the logging directory
