[Feature Request] Consider support int4/uint4 for reshape op of default CPU EP

### Describe the feature request

ONNX opset 21 added support for int4 and uint4 of reshape op. So I suppose default CPU EP should support int4 and uint4 data type for reshape op.

### Describe scenario use case

For WebNN use case, we need to insert `reshape` before scale and zeroPoint for dequantizeLinear implementation since ONNX constrains scale and zeroPoint(if exits) must be 1D tensor for per-axis dequantizeLinear. In some scenarios, the data type of zero_point is int4 or uint4.
