GUI: Display Seizure Warning popup for known applicable games

[BallM4788]

Prior to starting up games known to contain epileptic triggers such as rapid flashing or strobe effects, display a popup notifying the user of this, with an option to return to the launcher. Emphasis on "games known to contain": too many games are supported by ScummVM to dig through all at once. Therefore, the popup warning would need to be applied on a best-effort basis, added to games over time as they become known to contain epileptic triggers.

Mockup of popup contents:

If you have such a list of games, please provide them. I am not aware of any such list on any platform or distribution network such as Steam.

Please take into account that even in the supported list, there are currently over 800 games.
