In terms of being made specifically for WRX then GCK must be the biggest single outlay, most of the other cars have started from a base from someone else but the Megane is built from the ground up.
If we're talking money spent on RX, I can say with huge confidence that Peugeot have spent the most money and resource, closely followed by Audi and GCK. PSRX are a distant 4th. The VW and Hyundai had a lot of money spent on them in WRC but far less than competitors in RX - in terms of testing alone, Peugeot, GCK and Audi have done more test days each than PSRX, GRX and OMSE combined!
