/**
* \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.
* \warning This function is deprecated and will be removed in a
* future version of the library.
* To wrap a key into an opaque one the following functions
* should be used instead:
* - mbedtls_pk_get_psa_attributes()
* - mbedtls_pk_import_into_psa()
* - mbedtls_pk_setup_opaque().
*
* \param pk Input: the EC or RSA key to import to a PSA key.
* Output: a PK context wrapping that PSA key.
