9d0acb87 - [mlir][Vector] Add support for trunci to narrow type emulation (#82565)

[mlir][Vector] Add support for trunci to narrow type emulation (#82565) This PR add support for `arith.trunci` to vector narrow type emulation for iX -> i4 truncations, for X >= 8. For now, the pattern only works for 1D vectors and is based on `vector.shuffle` ops. We would need `vector.deinterleave` to add n-D vector support.
