[LV][EVL] Support fixed-order recurrence idiom with EVL tail folding. (#124093)

This patch converts the llvm.vector.splice intrinsic to
llvm.experimental.vp.splice, ensuring that fixed-order recurrences
execute correctly when tail folding by EVL is enable.
Due to the non-VFxUF penultimate EVL issue, the EVL from the previous
iteration will be preserved and used in llvm.experimental.vp.splice.
