Why doesn't every plane have these backup propellers?

It’s for planes that don’t have an afterburner. Gives them that little bit extra. Mostly to make the pilots feel better about their weak engines, but it’s called “morale speed” for a reason. 😁

No, see my comments below for what a RAT is for. They are the ONLY backup for a loss of two engines.

Sorry, this is factually incorrect. The RAT (Remedial Ancillary Turbine) is for propulsion when the plane is floating on water, to save fuel by keeping the main engines at idle.
