Ronald Cron c4d1b514ab Define handles as key identifiers
Define psa_key_handle_t to be equal to
mbedtls_svc_key_id_t. Make the handle of a persistent
key be equal to its key identifier. For volatile keys,
make the key handle equal to the volatile key
identifier of the created volatile key.

The unit tests are modified just to make them compile
not to make them run successfully. They are fixed in
the subsequent commits.

*
* This file contains platform-dependent type definitions.
*
* In implementations with isolation between the application and the
* cryptography module, implementers should take care to ensure that
* the definitions that are exposed to applications match what the
* module implements.
