Clean and clear CI

[IlyasMoutawwakil]

What does this PR do?

• Testing IPEX with torch from 2.2.0 to 2.4.*.
• Adding assertions for the tested versions of torch, IPEX and transformers.
• Distribute OpenVINO tests based on test file patterns to accelerate the CI.
• Use "latest" transformers version to avoid pinning a specific version in the CI that needs to be updated with each release.
• Reducing verbosity to use transformers testing utility whenever possible (nice reports):
