Problem description

Currently, matmul test suites can only be launched via sweeps_parameter_generator that uses custom harness including elastic cloud. This PR extends the change in previous PR that added the ability to locally run the tests using pytest.

What's changed

1. Create test_ functions that pytest can recognize and execute automatically.
2. Tie test_ to parameters declared as a dictionary
3. Keep a run function that passes all arguments to retain compatibility with existing testing infra.

Checks

1. pytest generated sweeps correlates with tests generated by sweep framework.

Known issue

Pytest handles all None values to be unique. This results in 1% additional duplicate tests in pytest. This is to be addressed in a separate PR as a low priority item.
