e7f21e65b6 Change J-PAKE internal state machine
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.

a9aab1a85b pk/psa: use PSA guard for mbedtls_ecc_group_to_psa() and mbedtls_ecc_group_of_psa()
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

637c049349 Move mbedtls_ecp_modulus_type out of the public headers
This is an internal detail of the ECC arithmetic implementation, only
exposed for the sake of the unit tests

Mbed TLS 3.4.0 was released with the type mbedtls_ecp_modulus_type defined
in a public header, but without Doxygen documentation, and without any
public function or data structure using it. So removing it is not an API
break.
