linqunAMD e78a897ec0 [CK] Add command option instance_index and param_mask to run partial ck test (#2889)
* [CK] Add command option instance_index and param_mask to run partial ck test

Many CK test are instance test. it will loop all instance in the instance library. It causes test often out-of-time if we run test on simulator/emulator.
This PR add option instance_index and param_mask to reduce the workload of instance test

instance_index: only run test 1 available instance with specified index.
param_mask: filter the embedded parameter with specified mask

* fix CI error

* fix clang format
