  [mlir][xegpu] Support subgroup layout assignment for scatter stores (#205955)

Add getStoreSubgroupLayouts() to derive the subgroup (sg_layout/sg_data)
anchor layout for store_scatter and store_matrix. It factorizes numSg
into the most balanced sg_layout that divides the workgroup tile with
sg_data a multiple of inst_data (lane_layout * lane_data).
