[AArch64][SelectionDAG] fix infinite loop caused by legalizing & combining CONCAT_VECTORS
Legalizing in `AArch64TargetLowering::LowerCONCAT_VECTORS()` and combining in `DAGCombiner::visitCONCAT_VECTORS()` could cause an infinite loop.
This commit fixes that issue by conditionally skipping the combining.
