  [mlir][ArmSME] Support vertical layout in load and store ops (#66758)

In SME a ZA tile slice is a one-dimensional set of horizontally or
vertically contiguous elements within a ZA tile. Currently the load and
store ops only support horizontal tile slices. This patch adds a tile
slice layout attribute to the load and store ops to support both
horizontal and vertical tile slices.

When lowering from Vector dialect horizontal layout is the default.
