fix test bugs for resize op version 11

[askhade]

Some of the tests have bugs where the model is not given the expected inputs.

For example test : resize_upsample_sizes_nearest_ceil_half_pixel
Expects the results with rounding mode as ceil however the model is not given this as input therefore during inferencing backends end up using the default rounding mode and the test fails.

@daquexian : I noticed the formula for coordinate transformation which is specified in the spec

onnx/onnx/defs/tensor/defs.cc

Line 1678 in 3ea3b0e

x_original = length_resized > 1 ? (x_resized + 0.5) / scale - 0.5 : 0, <br/>

is different than the one in the interpolate_1d method used in resize.py

onnx/onnx/backend/test/case/node/resize.py

Line 133 in 3ea3b0e

if output_width == 1:

onnx/onnx/backend/test/case/node/resize.py

Line 134 in 3ea3b0e

x_ori = -0.5

Can you clarify why it is different?

Either ways we need to change one so that they both match... If the change is needed in resize.py then I can add it to this PR... if it is required in defs.cc then we will need an opset bump

Nice catch. I think the changes is needed in defs.cc. The implementation in resize.py has been verified to be compatible with PyTorch here

This means we need to update the opset version for this change... I will include it as part of another PR.

There are more changes required in defs.cc for example :

Here scales is meant to be optional but it is not declared as optional... "OpSchema::Optional" needs to be explicitly specified for any optional inputs.

Line 1742 in 3ea3b0e

" be the same as the rank of input 'X'. Only one of 'scales' and 'sizes' can be specified. If 'size' is needed, the user can use an empty string as the name of 'scales' in this operator's input list.",

I am planning to make these changes as part of the next PR and bump up the opset version
