feat: parametrize_wrapper

[horw]

Description

Add idf_parametrize decorator to simplify pytest parametrization by handling target expansion and runner marks via string representation.

• Automatically expanding special target values ('supported_targets' and 'preview_targets') into individual test cases;
• Simplifying pytest mark usage by allowing string-based mark definitions instead of direct pytest.mark usage;
• Unifying the parametrization pattern across esp-idf test cases;

Let's add test cases for _expand_target_values, _process_pytest_value, and idf_parametrize itself. @hfudev, if you think some other cases should be covered, let me know, and I will add them.

Thanks for the PR, please also update our user guide with some examples!

not sure if it's feasible.
