Enable TurboModule interop in Bridgeless Mode (#39687)

Summary:
Pull Request resolved: #39687

Bridgeless mode is releasing in 0.73.

Bridgeless mode isn't stable inside RNTester (in 0.73) without the TurboModule interop layer: T164853040.

**Changes:** Enable the TurboModule interop layer in RNTester (Bridgeless Mode).

**Urgency:** This will unblock the 0.73.
