Enhance APK, AAB, and IPA path validation in sentry_upload_build

- Added default values for apk_path, aab_path, and ipa_path parameters.
- Improved verification logic to skip validation for nil or empty values.
- Ensured proper error handling for invalid paths and file types.

This update refines the user experience by preventing unnecessary errors during configuration.
