[SilOpt] Add new layout type _TrivialStride and add pre-specialization suppport for it (#70308)

Browse Source 
rdar://119329771

This layout allows adding pre-specializations for trivial types that have a different size, but the same stride. This is especially useful for collections, where the stride is the important factor.
