Expose EditorExport

[DexterFstone]

Resolves godotengine/godot-proposals#13865

[AThousandShips]

What are these changes for? They seem unrelated and would be good to document why

[DexterFstone]

Well, previously, some checks failed, I thought it was because of this, but if this is not the case, I can reverse it

[AThousandShips]

Probably something incorrect with the usage, but that's okay, I think it's because of the order of creation

@AThousandShips I know 4.6 is feature freeze, but is it possible to merge this? It's not a very big change. I need this change, and I don't want to use a custom build for my team work, and I don't want to wait for 4.7

I have some random crashes

This will not be merged in 4.6, you can build it for your own branch though, but if it is approved it won't be available until 4.7 at the earliest
