Per-game sync paths

[AkazaRenn]

It can help reducing the sync time by only syncing necessary files instead of all of them. My idea is that we can add an entry to the game context menu like CheatDeck and SteamGridDb do, that would be where the per-game sync paths are modified. We can reuse our current sync paths page for that, maybe add toggles for bi-sync and sync before launch, after close, etc. And we don't need to check whether the game supports Steam Cloud or not anymore.

As for storing the configs, we can save them in individual directories named by the app ID, so it would be like /home/deck/homebrew/settings/Steam-Cloud-Save/123456/filter.txt etc. Logs can be separated too if necessary.

We can keep our current sync path settings as the global one and it will be excuted together with the per-game ones, so nothing would change just by updating.

It's not gonna be as good as your ludusave project since things still need to be setup manually, but it feels like a step forward. I kinda have an idea and can look into it during the holidays, my company is approaching the release so the air is a bit of tight rn 🫠.
