LOG: [TTI][RISCV] Add cost modelling for intrinsic vp.load.ff (#160470)
Split out from #151300 to isolate TargetTransformInfo cost modelling for
fault-only-first loads from VPlan implementation details. This change
adds costing support for vp.load.ff independently of the VPlan work.
For now, model a vp.load.ff as cost-equivalent to a vp.load.
