Keep track of the J-PAKE internal state in a more intuitive way.
Specifically, replace the current state with a struct of 5 fields:
* The round of J-PAKE we are currently in, FIRST or SECOND
* The 'mode' we are currently working in, INPUT or OUTPUT
* The number of inputs so far this round
* The number of outputs so far this round
* The PAKE step we are expecting, KEY_SHARE, ZK_PUBLIC or ZK_PROOF
This should improve the readability of the state-transformation code.

This allows also to:
- removing the dependency on ECP_C for these functions and only rely
on PSA symbols
- removing extra header inclusing from crypto_extra.h
- return MBEDTLS_PK_USE_PSA_EC_DATA and MBEDTLS_PK_HAVE_ECC_KEYS to
their original position in pk.h

This is only partial support. Only 'client' and 'server' values are accepted for peer and user.
Remove support for role.

- 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.

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.

Additionally use psa_get_and_lock_key_slot_with_policy() to obtain key.
This requires making this function public. This will have to be solved while adding driver dipatch for EC-JPAKE.

This macro is specific to the Mbed TLS implementation and not part of
the public API, so it shouldn't used the PSA_ namespace.

The format used by the mbedtls_ecjpake_xxx() APIs and that defined by
the PSA Crypto PAKE extension are quite different; the former is
tailored to the needs of TLS while the later is quite generic and plain.
Previously we only addressed some part of this impedance mismatch: the
different number of I/O rounds, but failed to address the part where the
legacy API adds some extras (length bytes, ECParameters) that shouldn't
be present in the PSA Crypto version. See comments in the code.
Add some length testing as well; would have caught the issue.
