Support shared component with next built-in client components

[huozhi]

Fixes #35449

Include the shared components (from source code) is in client bundles, previously we lost them so that the client components imported by them are lost in module graph

• let flight server loader apply to all pages and imported modules (except node_modules at the moment)
• if it's a shared component from source code, include it in client bundle
• ignore handling node_modules at the moment (due to the limitation support of esm imports with RSC)
