Enhance branch extension logic to handle __objc_stubs identically to __stubs The branch extension algorithm currently has specific handling for the `__stubs` section: 1. It ensures all `__stubs` content is directly reachable via branches from the text section. 2. It calculates the latest text section address that might require thunks to reach the end of `__stubs`. The `__objc_stubs` section requires precisely the same handling due to its similar nature, but this was not implemented. This commit generalizes the existing logic so it applies consistently to both the `__stubs` and `__objc_stubs` sections, ensuring correct reachability and thunk placement for both. Without this change it's possible to get relocation errors during linking in scenarios where the `__objc_stubs` section is large enough.
