  -----------
  [MLIR][XeGPU] Support pointer/dynamic-memref sources in array-length optimization (#195872)

Extend `OptimizeCreateNdDescOp` to handle the two remaining
`create_nd_tdesc` source forms — `i64` pointer and dynamic-shape memref
— by forwarding the existing shape/strides operands through the general
builder. The memory region is unchanged by the rewrite; only the
`tensor_desc` view is narrowed along the FCD and tagged with
`array_length`.
