eff5b9a7 - Remove training packages from onnxruntime-ios-packaging-pipeline (#25451)

Remove training packages from onnxruntime-ios-packaging-pipeline (#25451) ### Description remove support for multiple package variants (`Full` and `Training`) in the Apple packaging pipeline, consolidating the codebase to only support the `Full` variant. The changes simplify the code by eliminating the `PackageVariant` enum, related logic, and configuration files for the `Training` variant. --------- Co-authored-by: Edward Chen <18449977+edgchen1@users.noreply.github.com>
