Integrators in a client-server architecture need to provide this function on
the client side.

As the definition of psa_pake_operation_s has
been moved the "xyt_t" structure types can not
be used anymore (defined later).

In crypto_extra.h, move PAKE size calculation macros,
the definition of psa_pake_cipher_suite_s and
psa_pake_operation_s just after PAKE type and values
definitions.
This aligns with the order of crypto header inclusions
in crypto.h: crypto_types.h, then crypto_values.h,
then crypto_sizes.h, and then crypto_struct.h.
Take care of keeping them outside of the pake Doxygen
group as they used to be.

This allows any implementer of the PSA client interface to easily
include this header and therefore function's prototype.

MBEDTLS_PSA_KEY_BUFFER_MAX_SIZE is only used in tests so it should
not be defined in a public header such as "crypto_extra.h".
"psa_crypto_helpers.h" is a better option.

Instead of skipping some tests when !MBEDTLS_PSA_STATIC_KEY_SLOTS,
add a proper check in the depends_on to verify if
MBEDTLS_PSA_KEY_BUFFER_MAX_SIZE is actually large enough to contain
the key used in such test.

Move the default definition of MBEDTLS_PSA_STATIC_KEY_SLOT_BUFFER_SIZE
from psa_crypto_core.h to the public header crypto_extra.h in order

Restricting the built-in key range would be an API break since applications
can hard-code a built-in key value and expect that it won't clash with
anything else. Make it harder to accidentally break the API.

mbedtls_psa_register_se_key() is not usable with volatile keys, since there
is no way to return the implementation-chosen key identifier which would be
needed to use the key. Document this limitation. Reject an attempt to create
such an unusable key. Fixes#9253.

In `psa_key_attributes_t`, keep track of whether `slot_number` has been set
through a dedicated field, rather than using a flag.
This paves the way to removing `flags`, which is not used for anything else.

Access the fields of `psa_key_attributes_t` directly rather than through the
`core` field. This makes the `core` field obsolete.
This commit is fully automated:
```
git ls-files '*.h' '*.c' '*.function' '*.jinja' | xargs perl -l -i -pe '$core = qr/\b(core\b|MBEDTLS_PRIVATE\(core\))/; s/->$core\./->/g; s/&(\w+)\.$core\./&$1./g; s/(\w+)\.$core/$1/g'

Move the `slot_number` field of `psa_key_attributes_t` to
`psa_core_key_attributes_t`. This makes ``psa_core_key_attributes_t` core`
the sole field of `psa_key_attributes_t`. This paves the way to unifying
the two structures.

This function, and mbedtls_psa_crypto_free, are not thread safe as they wipe slots
regardless of state. They are not part of the PSA Crypto API, untrusted applications
cannot call these functions in a crypto service.
In a service intergration, mbedtls_psa_crypto_free on the client cuts the communication
with the crypto service.

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
