e12ed36a6c Move JPAKE state machine logic from driver to core
- 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.

51eac53b93 Divide pake operation into two phases collecting inputs and computation.
Functions that only set inputs do not have driver entry points.
