  [AArch64] Preserve SDNode flags when lowering fixed vectors to scalable operations (#204616)

Preserve the original SDNode flags when LowerToScalableOp rebuilds fixed-length vector operations using their scalable container type. This allows combines to use flag information generated before the scalable was created.
