Pull request overview

This PR adds utility functions to retrieve the oneDNN version from the library and expose it through the testing interface.

Changes:

• Implements a C++ function get_onednn_version() that queries oneDNN for its version information
• Exposes the version function through PyTorch bindings for use in Python tests
• Adds a test to verify the oneDNN version matches expected values

Hard-coded version values should be extracted as constants at the module level or read from configuration to make version updates easier to maintain.

The inner scope block appears unnecessary. The ver variable could be declared directly without the extra braces.

Suggested change

	{
	const dnnl_version_t* ver = dnnl_version();
	ss << ver->major << '.' << ver->minor << '.' << ver->patch << "."
	<< ver->hash;
	}
	const dnnl_version_t* ver = dnnl_version();
	ss << ver->major << '.' << ver->minor << '.' << ver->patch << "."
	<< ver->hash;
