new granulated overmap view doesn't support variants and multitiles

[vetall812]

Describe the bug

PR #75236 do not draw variants and / or multitiled sprited for the new granulated overmap objects.

As you can see on the following screenshot it always take the first sprite. The green tile with numbers 01 are the tileset objects "forested$vague" and "forested$outlines" and spruces are "forested$details" that doesnt have special tileset object but use "look_like" mechanics instead. You can also see normal forest near the road - this forest use tileset variants as expected:

PS. Tileset is still WIP, but can be obtained for testing purposes.
