Sergey Kachkov 8201cf311a [TTI][CostModel] Add cost modeling for expandload and compressstore intrinsics (#122882) ...

This patch adds methods for cost estimation for
llvm.masked.expandload/llvm.masked.compressstore intrinsics in TTI. If
backend doesn't support custom lowering of these intrinsics it will be
processed by ScalarizeMaskedMemIntrin so we estimate its cost via
getCommonMaskedMemoryOpCost as gather/scatter operation; for RISC-V
backend, this patch implements custom hook to calculate the cost based
on current lowering scheme.
