[factory] Fully initialize StackFrameInfo for GC verifier safety

Factory::NewStackFrameInfo was leaving fields with the default
initialization to 'undefined' for fields marked as Smi type in base.tq.
Our heap verifier dutifully found and reported the discrepancy. This CL
initializes all fields of the struct to values compatible with the Torque
specification. In the future, this should probably be done automatically.
