f62b3bb087 Optimization of pake core functions
Adapt pake test (passing NULL buffers is not allowed).
Passing the null buffer to psa_pake_output results in a hard fault.

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.

ed73355d2e Make \retval commands non-empty
Pacify Clang >=15 which complained:
```
include/psa/crypto.h:91:23: error: empty paragraph passed to '\retval' command [-Werror,-Wdocumentation]
 * \retval #PSA_SUCCESS
   ~~~~~~~~~~~~~~~~~~~^
```

This commit performs the following systematic replacement:
```
perl -i -0777 -p -e 's/([\\@])(retval +\S+)\n(?! *\*? *([^\n \\*\/]|\\[cp]\b))/$1$2 ${1}emptydescription\n/g' $(git ls-files '*.[hc]' '*.function' '*.jinja')
```
i.e. add an `\emptydescription` argument to `\retval` commands (or
`@retval`, which we don't normally used) that are followed by a single word,
unless the next line looks like it contains text which would be the
description.

6d40e54db0 Split the high nesting of BignumModRawConvertRep.generate_function_tests
Pylint complains about the nesting. It's not wrong.

No behavior change.

342b9a903d bignum_mod_raw.py: Added a filtering logic to BignumModRawConvertRep.generate_function_tests()
This patch introduces a hybrid approach to input_styles, and will remove the
dependency requirements from test cases with `ModulusRepresentation.OPT_RED`

As a result it is reducing testing input duplication.

ae4d2cf3e3 bignum_common.py: Introduce the set_representation setter.
This patch adds the default representation attribute through a
setter() method in `BignumModRawConvertRep()`

It also adds standard common template properties:
    symbol = ""
    input_style = "arch_split"
    arity = 1

ad335b55ff Fix representation conversion with 32-bit limbs
The Montgomery representation depends on the limb size. So the
representation conversion test cases need separate 64-bit and 32-bit cases
when the representation is Montgomery.
