Remove enableFabricRenderer feature flag (#56909)

Summary:

The `enableFabricRenderer` feature flag has been removed; it was always set to true on the canary release stage and there are no remaining callers (all inlined in earlier diffs of this stack).

This diff:
- Removes the `enableFabricRenderer` entry from `ReactNativeFeatureFlags.config.js`.
- Updates the description of `enableBridgelessArchitecture` (which referenced `enableFabricRenderer`).
- Regenerates the codegen output: the 7 Kotlin `generated` files in `ReactAndroid/src/main/java/com/facebook/react/internal/featureflags/`, the C++ headers and implementations under `ReactCommon/react/featureflags/` and `ReactCommon/react/nativemodule/featureflags/`, the JNI bridge under `ReactAndroid/src/main/jni/react/featureflags/`, and the JS modules under `src/private/featureflags/`.

The flag is in the `com.facebook.react.internal.featureflags` package and is excluded from `ReactAndroid.api` tracking; no API metadata regeneration is needed.

Behavior is unchanged.

Changelog:
[Android][Removed] - Remove `enableFabricRenderer` feature flag — Fabric is now always enabled
