66a0a081 - [RISCV] Extract spread(2,4,8) shuffle lowering from interleave(2) (#118822)

[RISCV] Extract spread(2,4,8) shuffle lowering from interleave(2) (#118822) This is a prep patch for improving spread(4,8) shuffles. I also think it improves the readability of the existing code, but the primary motivation is simply staging work.
