[WIP][TTI] Replace getStridedMemoryOpCost with getIntrinsicInstrCost

[arcbbb]

In #160470, there is a discussion about the possibility to explored a general approach for handling memory intrinsics.

This patch adds alignment to IntrinsicCostAttributes for type-based cost queries used by SLP and Loop Vectorizer before IR is materialized.

Candidates to adopt this are getMaskedMemoryOpCost, getGatherScatterOpCost, getExpandCompressMemoryOpCost, and getStridedMemoryOpCost.
