- Make ExtensionPointFactoryMiddleware an opaque type via new
@internal/backend package using OpaqueType from @internal/opaque
- Use options object for createExtensionPointFactoryMiddleware
- Make middleware function async (returns Promise<T>)
- Remove extensionPointFactoryMiddleware from createBackend, keep only
on createSpecializedBackend
- Export defaultServiceFactories from @backstage/backend-defaults

Allow the backend to reimplement extension point outputs at creation
time via a new extensionPointFactoryMiddleware option on createBackend().
Each middleware entry declaratively targets a specific extension point
by reference and the framework handles matching and pass-through
automatically.
