  [RISCV] Unify RVBShift_ri and RVBShiftW_ri with Shift_ri and ShiftW_ri. NFC (#111263)

The split primarily existed because Shift_ri and ShiftW_ri included
scheduler classes. So pull those out like ALU_rr.

This removes all uses of RVBShiftW_ri. One use of RVBShift_ri remains
because SLLI_UW uses a uimmlog2xlen shift amount and OP_IMM_32. Which is
different than the other OP_IMM_32 shift instructions.
