[FIX] Handle checking 'installed_games' file for Crossover

[arielj]

Back in November, an installed_games metadata file was introduced to detect when a new game is installed in an already created prefix. This was not handling Crossover bottles properly, since it was always using the configured winePrefix of the settings that is not used for Crossover.

This PR adds the handling of that, creating the installed_games file inside the bottle's folder (essentially a wine prefix) by using some verbose crossover output.

One thing to note is that this will trigger the installation of redistributables once for each game that's already installed since the installed_games file is not there yet, but the same is happening now in linux.

This fixes #4369
