Move JPAKE state machine logic from driver to core

Browse Source 
- Add `alg` and `computation_stage` to `psa_pake_operation_s`.
  Now when logic is moved to core information about `alg` is required.
  `computation_stage` is a structure that provides a union of computation stages for pake algorithms.
- Move the jpake operation logic from driver to core. This requires changing driver entry points for `psa_pake_output`/`psa_pake_input` functions and adding a `computation_stage` parameter. I'm not sure if this solution is correct. Now the driver can check the current computation stage and perform some action. For jpake drivers `step` parameter is now not used, but I think it needs to stay as it might be needed for other pake algorithms.
- Removed test that seems to be redundant as we can't be sure that operation is aborted after failure.
