fix: Refactors getting static tiles to use enumerators (#1611)

Browse source 
### Summary
* Refactors getting static/multi tiles to not use allocations.
* `TileList` is now only used during bootstrapping and uses rented buffers to eliminate extra allocations.
* Replaces `StaticTile[] GetStaticTiles` with:
    ```cs
        Map.StaticTileEnumerable GetStaticTiles(int x, int y);
        Map.StaticTileEnumerable GetStaticAndMultiTiles(int x, int y);
        Map.StaticTileEnumerable GetMultiTiles(int x, int y);
    ```
* Removes `Synchronized` and `lock` from TileMatrix. It is no longer considered a multi-thread safe system.
