944e031e - [mlir][mesh] Use tensor shape notation for the shape of a cluster (#73826)

[mlir][mesh] Use tensor shape notation for the shape of a cluster (#73826) Examle: substitute mesh.cluster @mesh0(rank = 2, dim_sizes = [0, 4]) with mesh.cluster @mesh0(rank = 2, dim_sizes = ?x4) Same as tensor/memref shapes. The only difference is for 0-rank shapes. With tensors you would have something like `tensor<f32>`. Here to avoid matching an empty string a 0-rank shape is denoted by `[]`.
