Use "version" project setting as macOS/iOS "short_version" fallback.

Fixes #83684

Both short_version and version are using the same format ([Major].[Minor].[Patch], but full version can include additional integers), so the same fallback can be used.

We probably should also add build_nr project settings (which is autoincremented on export) and append it to the full macOS/iOS version. I'll check what's the expected version formats on other platforms later (at least Windows seems to be 4 ints, so it can auto use build_nr too, Android seems to use versionCode for the same purpose).

I think this sounds like a very good idea, and have "Short version" default to the project version setting and "Version" default to the project version setting+this new build_nr. You might have to investigate if appstore submissions support four-component versions like windows though. It didn't in the past, and invalid versions will block submission. But this might have changed.
