  [RISCV][TTI]Use processShuffleMasks for cost estimations/actual per-register shuffles

Patch adds usage of processShuffleMasks in TTI for RISCV. This function is already used for X86
shuffles estimations and in DAGTypeLegalizer::SplitVecRes_VECTOR_SHUFFLE
functions and in RISCV codegen.
Patch allows better cost estimation for sparse masks and unifies
cost/codegen between different targets/passes
