[RISCV] Fold add_vl into accumulator operand of vqdot* (#139484)

If we have a add_vl following a vqdot* instruction, we can move the add
before the vqdot instead. For cases where the prior accumulator was
zero, we can fold the add into the vqdot* instruction entirely. This
directly parallels the folding we do for multiply add variants.
