[UX] Add support for autoinstallation of files from game folder

[arielj]

This PR extends the feature that applies automatic winetricks fixes by supporting also automatic run exe in prefix actions.

Sometimes, some games include files that has to be executed that are not listed as prerequisites. The most common case is FallGuys that requires the installation of the EpicOnlineServices to solve the Missing Files error.

This can be used for any game that needs a similar tweak by adding content in the https://github.com/Heroic-Games-Launcher/known-fixes repo.

You can use Fall Guys to test this feature.
