4a094095 - [MLIR] Make 1-D memref flattening a prerequisite for vector narrow type emulation (#157771)

[MLIR] Make 1-D memref flattening a prerequisite for vector narrow type emulation (#157771) Addresses: https://github.com/llvm/llvm-project/issues/115653 We already have utilities to flatten memrefs into 1-D. This change makes memref flattening a prerequisite for vector narrow type emulation, ensuring that emulation patterns only need to handle 1-D scenarios.
