  [RISCV] Implement RISCVInstrInfo::getMemOperandsWithOffsetWidth (#73681)

This hook is called by the default implementation of
getMemOperandWithOffset and by the load/store clustering code in the
MachineScheduler though this isn't enabled by default and is not yet
enabled for RISC-V. Only return true for queries on scalar loads/stores
for now (this is a conservative starting point, and vector load/store
can be handled in a follow-on patch).
