  [mlir][xegpu] Add SIMT distribution support for GEMM transpose B case.  (#155517)

This PR adds the features needed for supporting the GEMM with transpose
B case.

Summary of changes.

1). Add distribution logic for `vector.bitcast`, `vector.transpose` and
`memref.extract_aligned_pointer_as_index` cases.
2). Add layout propagation support for `vector.shape_cast`,
`vector.broadcast` and `vector.bitcast`
3). Incorporate slice attribute and `DistributeLayoutAttr` interface
with the core logic in layout prop.
