test_operator_gpu.test_convolution_with_type has fixed seed that can mask flakiness

[szha]

The unit test in title have been using fixed seed to mask flakiness. Suggested action:

1. Evaluate whether the test is flaky without fixed seed. If not, remove seed. Else move to 2
2. If test is flaky, determine whether it's an actual uncaught edge case. If so, fix the operator. Else move to 3
3. If numerical instability is inevitable, adjust tolerance level appropriately.

@szha Thanks for filing this issue. We will investigate these Flaky tests.

Removed the seed and ran test for 100K no issue here, will submit a PR removing the seed with another test I am looking into
