Reorganize Inference CI tests

[akashmjn]

In V1 code within InferenceSystem/tests there is:

Component tests (~10s):

• test_audio_processing
• test_model_inference

Integration tests (~10min):

• test_orchestrator_v1
  • has reliable tests (positive, negative, failures)
  • flaky live HLS test

Currently integration tests are run cross platform (ubuntu, windows) in CI.

Follow ups:

1. Add lighter component tests as two cross platform jobs
2. Factor out slow/flaky Live HLS integration test as a separate CI job
3. Decide if duplicating integration tests (incl flaky one) in cross platform jobs

Generally fine to test much as needed as long as it doesn't get too bloated/flaky/slow to contribute.
