Removals
* Temporary function mbedtls_pk_wrap_as_opaque() is removed. To mimic the
same behavior mbedtls_pk_get_psa_attributes() and
mbedtls_pk_import_into_psa() can be used to import a PK key into PSA,
while mbedtls_pk_setup_opaque() can be used to wrap a PSA key into a opaque
PK context.

* \brief Turn an EC or RSA key into an opaque one.

* \warning This is a temporary utility function for tests. It might
* change or be removed at any time without notice.
*
* \param pk Input: the EC or RSA key to import to a PSA key.
* Output: a PK context wrapping that PSA key.
* \param key Output: a PSA key identifier.
* It's the caller's responsibility to call
* psa_destroy_key() on that key identifier after calling
* mbedtls_pk_free() on the PK context.
* \param alg The algorithm to allow for use with that key.
* \param usage The usage to allow for use with that key.
* \param alg2 The secondary algorithm to allow for use with that key.
*
* \return \c 0 if successful.
* \return An Mbed TLS error code otherwise.
