Pull Request Overview
This PR enables lightweight marshalling for enum types in WebAssembly builds. The fix addresses a runtime marshalling issue where enums were not being recognized as supported types by the lightweight marshaller, even though they were marked as marshallable during the build process.
Key changes:
- Updated runtime marshalling logic to recognize enums as lightweight-marshallable types
- Added test coverage for enum marshalling through ZipArchive interop functionality

Based on
MinimalMarshalingTypeCompatibilityProvider.cswe mark enums as marshallable by lightweight marshaller on build.We were missing enums when checking for supported types in
marshal-ilgen-stub.con runtime.Fixes #115780
Contributes to #94187
