[PATCH 18/20] s390: Rename insn format RRR_FE0FEFE to RRF_FE0FEFE

This patch renames the S/390 instruction format RRR_FE0FEFE to RRF_FE0FEFE. The change is motivated by architectural updates where the RRR format has been effectively merged into the RRF-a format since the IBM z196 processor. This renaming ensures that the opcode definitions accurately represent the current instruction set architecture.
