  [RISCV][TTI] Factor out getVSlideCost helper [nfc]

Reasonable implementations may differ in complexity cost, so doing some API prepwork to support tunables.  Note that this patch only covers the cases where we model the slide cost as linear.  A separate patch will propose changing our insert and extract costs from constant-in-lmul to linear-in-lmul.
