Reapply "[RISCV][TTI] Add shuffle costing for masked slide lowering (#128537)"
With a fix for fully undef masks. These can't reach the lowering code, but
can reach the costing code via e.g. SLP.
This change adds the TTI costing corresponding to the recently added
isMaskedSlidePair lowering for vector shuffles. However, since the
existing costing code hadn't covered either slideup, slidedown, or the
(now removed) isElementRotate, the impact is larger in scope than just
that new lowering.
