fix(build): Improve error for xcarchive/IPA uploads on non-ARM64

When users try to upload .xcarchive or .ipa files from a non-Apple
Silicon Mac (e.g. Intel-based Xcode Cloud), they get a confusing error
that only mentions Android formats (APK, AAB). The real reason is that
xcarchive/IPA processing is compile-time gated to ARM64 macOS.

Add a targeted check on non-ARM64 platforms that detects these file
extensions and returns a clear error explaining the Apple Silicon
requirement.
