[test] Add unit tests for ACP and ALRU cleaning policy parameters

Browse Source 
- Add tests for wake-up and flush-max-buffers parameter validation
- Test parameter boundary values and error conditions
- Cover parameter parsing from configuration strings
- Verify set_param_cleaning_policy commands construction
- Test proper handling of different cleaning policies in configure_cache

These tests ensure the proper validation and handling of cleaning policy
parameters introduced in the previous commits.
