[Relax] Fix flaky test_conv2d_offload by increasing float32 tolerance (#18455)

The `test_conv2d_offload` test for float32 dtype was intermittently
failing in CI with errors like:
```
Mismatched elements: 17 / 524288 (0.00324%)
Max absolute difference: 0.02001762
Max relative difference: 3193.5
```
The test was using `rtol=1e-2, atol=1e-2` (0.01) tolerance, which may be
too strict for comparing cuDNN and LLVM implementations. The max
absolute difference of ~0.02 exceeded the threshold, causing flaky test
failures. This PR increases the tolerance for float32 from `1e-2` to
`2.5e-2` (0.025) to accommodate the observed numerical differences
between cuDNN and LLVM convolution implementations.
