[mlir][Vector] Replace `vector.shuffle` with `vector.interleave` in vector narrow type emulation (#82550)

This PR replaces the generation of `vector.shuffle` with
`vector.interleave` in the i4 conversions in vector narrow type
emulation. The multi dimensional semantics of `vector.interleave` allow
us to enable these conversion emulations also for multi dimensional
vectors.
