bdec4da3 - [RISCV][P-ext] Only support sshlsat for splat immediate shift amounts. (#184886)

[RISCV][P-ext] Only support sshlsat for splat immediate shift amounts. (#184886) Fixes cannot select errors for other types of shift amounts. I've made a new RISCVISD node that only allows an immediate operand. It's assumed that the lowering code will only allow valid immediates so I'm not using a TImmLeaf in the match.
