Avoid race conditions while launching games directly from the command line (#7116)

* optimization: Load application metadata only for applications with IDs

* Load applications when necessary

This prevents loading applications when launching an application
directly from the command line (or a shortcut).
Instead, applications will be loaded after the emulation was stopped by the user.

* Show the title in the configured language when launching an application

* Rename DesiredTitleLanguage to DesiredLanguage
