fix: add layer property to consumed module results from shareConfig

- Add layer property injection in webpack-bundler-runtime consumes.ts and installInitialConsumes.ts
- Handle existing layer properties gracefully to avoid read-only property errors
- Enables layers-consume-loader tests to pass by exposing layer info in module exports
