NaN for `[N, C, 1, W]` interpolate inputs with bilinear and bicubic modes for burn-wgpu and burn-ndarray backends

[antimora]

Describe the bug NaN values when the input tensor is [N, C, 1, W] shape.

To Reproduce

1. Enable test_1d_bilinear test in crates/burn-tensor/src/tests/module/bilinear_interpolate.rs and test_1d_bicubic in crates/burn-tensor/src/tests/module/bilinear_interpolate.rs which are ignored for now. (Copy of tests are in the comments)
2. cd burn-wgpu && cargo test
3. cd burn-ndarray && cargo test
4. Enable resize_with_scales_1d_linear test in crates/burn-import/onnx-tests/tests/onnx_tests.rs which is ignored.

NOTE:

These tests work under burn-tch and pytorch.
