[DevTools] Infer name from stack if it's the generic "lazy" name (#34907)
Stacked on #34906. Infer name from stack if it's the generic "lazy" name. It might be wrapped in an abstraction. E.g. `next/dynamic`. Also use the function name as a description of a resolved function value. <img width="310" height="166" alt="Screenshot 2025-10-18 at 10 42 05 AM" src="https://github.com/user-attachments/assets/c63170b9-2b19-4f30-be7a-6429bb3ef3d9" />
