Compatibility rework 2

[rankynbass]

Replacement compatibility rework to go with PR goatcorp/FFXIVQuickLauncher#1366.

This allows for the selecting of different wine versions, different dxvk versions, and hud options to all be managed on the XL.Core side. The values are then passed to CompatibilityTools. This primarily allows for updating wine or dxvk without touching XL.Common.Unix.

Replaces #59

Here's a flatpak of the launcher, for testing: https://github.com/rankynbass/XIVLauncher.Core/releases/tag/compatrework-v2

Wine folders can now be dropped in compatibilitytools/wine and dxvk folders can be dropped in compatibilitytool/dxvk, and they will now appear in the drop down lists. This basically replaces an enum with a dictionary, which is a lot more flexible and requires a lot fewer switch statements. Should be easier to update when new versions of wine or dxvk are released.

Updated for the XL.Common.Unix merge.

Conceptually I find it makes more sense to have OSInfo live in XIVLauncher.Common (this also gets rid of passing around that extra Flatpak bool).

Given that XL changes are rather hard though, it might be worth to put it for now into something like XIVLauncher.Common2, which would also allow to extend the existing interface more easily in the future (including auto-launch features)

Honestly, OSInfo could just be renamed DistroInfo, because that's all it's really doing. Yeah, it has checks for other OSes, but those aren't actually used for anything. It could just as easily be an IsLinux bool instead of an a platform enum. As for the flatpak bool, tbh it's not used for anything either. I mainly added it just in case, but never found any reason to use it in CompatibilityTools. All of the flatpak stuff has to be worked out before it gets passed to CompatibilityTools anyway.

[marzent]

If the Flatpak bool is truly not needed, then it should probably just be removed honestly.

But even as DistroInfo it does make much more sense to have it conceptually there (and could for example greatly simplify MangoHudIsInstalled).

In this MR as it is right now, it is used however much more like a more advanced OSVersion.
