Refactor MSB gen to consolidate interior/exterior code

[sbodegraven]

Created interfaces for Tiles and InteriorGroups/Chunks to consolidate a lot of MSB generation code used by both. Related issue: #47

I tried to keep the behaviour identical to before and it seems to be working correctly.

I haven't reviewed the logic deeply for Main.cs, but in general for C# you can make a lot of these more straightforward interface functions into arrow operator style, e.g.
public int GetMap() => map;
or into property style

public interface IMSBCompilableGroup
{
    int Map { get; }
}

public class InteriorChunk : IMSBCompilableGroup
{
    int Map { get; set; } // can get rid of map member and change references to this
}

Thanks, I forgot you could do that in C#. I've updated it to use the property style.

I've cleaned up some additional stuff, I'll leave it at that for now unless other changes are requested.

You can do inline initialization of properties to clean this up a little,
public List<AssetContent> Assets { get; init; } = [] (this one might cause a compiler error if you are initializing in a constructor)
or
public List<AssetContent> Assets { get; } = [] if there are no constructors that do anything other than a simple init

[sbodegraven]

Done.

[horfius]

This whole section is well cleaned up, but I want @infernoplus to take a look and see if there are cases where the logic should be separated a bit.

Why is this behind group.IsInterior now? I can't think of an exterior bed in all morrowind but we don't want to possibly exclude mods.

[sbodegraven]

All of the code blocks like this that reference rootCollision were previously only in the interior loop, so I had to add this check to maintain the same behaviour. It's possible that this is unnecessary and works fine for exteriors, but I don't know enough about it to make that call.

[horfius]

You should use this style instead of GetType and typeof.
else if (group is HugeTile || group is BigTile)

[sbodegraven]

Done.

[horfius]

Why put this behind group.IsInterior? Exteriors need collision assigned.

[sbodegraven]

This was only done for interiors before so I kept that the same.

[horfius]

You should make these Is_Condition_ consistent, either functions or property style.

[sbodegraven]

Done.
