  [AArch64][SVE] Handle multi-vector load/store opcodes in frame-index elimination

Lowering a wide scalable load from a stack object produces an
LD1*_{2Z,4Z}_IMM[_PSEUDO] with a frame-index base. getMemOpInfo() and getLoadStoreImmIdx()
had no entries for these SME2/SVE2p1 multi-vector opcodes, so PEI crasheds.
