add test_onnx_ops.py (#8569)

* boom

* fix webgpu

* use exact variable names in test so that AI can read easier

* add tag for specific test name like test a specific dtype

* fix ruff

* astype everything

* dtype in array creation

* just arange

* is 67% considered fixed?

* move test up

* small cleanups

* share function

* add qgemm as well

* add qgemm too

* make sure qgemm comes out as int

* take out qgemm for now

* fixed test

* add correct qgemm

* addressing feedback here too, early naive fix for now

* simplify bias and c to be minimalistic enough to test correctness

* refactored qlinearops

* maybe these asserts aren't the best..

* fix test

* updated tests to cover new ops

* try to add to CI

* move test_onnx_ops into testextra/

* more attention tests

* qlinear_add atol=1

* attention still not fullllllly correct

* it is what it is
