LOG: [MLIR][XeGPU] Extend op definitions to support    3D+: dpas, dpas_mx (#199809)

**Summary**

Extend xegpu.dpas and xegpu.dpas_mx operations to support 3D and 4D
operands with batch dimensions, enabling batched matrix multiplication
workloads like [4, 128, 512] x [4, 512, 128] -> [4, 128, 128].

  **Changes**

- Type definitions: Extended XeGPU_DpasOprType and XeGPU_DpasResType to
support rank 3-4 (previously 1-3 and 1-2)
- Op definitions: Extended dpas_mx scale operands to support rank 3-4
vectors
- Verifiers: Updated verifyDpasDimensions() to validate batch dimensions
across A, B, and result operands; updated DpasMxOp::verify() for
batch-aware scale dimension checks
- Documentation: Added comprehensive documentation explaining batch
dimensions, microarchitecture-specific matrix sizes, and 3D/4D usage
examples
  - Tests: Added unit tests for 3D batched dpas and dpas_mx operations
