This PR fix ROI values when tensor ROI is Empty pass Constant node in Resize
Operator
### Description:
- Fix ROI values when tensor ROI is Empty pass Constant node
- Create test with Constant and Tensor ROI is Empty
### Step to Reproduce:
- Deploy yolov5n.onnx using TVM. When executing
relax.transform.LegalizeOps() is happen error: "IndexError: list index out of
range" at roi array, because roi = []
- Error log:
> "File ~/Contributes/tvm/python/tvm/topi/image/resize.py:615, in
_resize_2d()
> 608 in_x = x1 * (image_width - 1) + w_scale * x
> 609 else:
> 610 in_x = get_inx(
> 611 x,
> 612 image_width,
> 613 target_width,
> 614 coordinate_transformation_mode,
> --> 615 roi[1],
> 616 roi[3],
> 617 width_use_int_div,
> 618 )
> 619 in_y = get_inx(
> 620 y,
> 621 image_height,
> (...) 626 height_use_int_div,
> 627 )
> 629 if method == "nearest_neighbor":
> IndexError: list index out of range"

### Resolve:
- On the Frontend, when encountering a case where ROI is constant and ROI is
empty, the handling is the same as when ROI = None (fill in the ROI tensor with
0.0).
