cf56a0a320 psa: Move from key handle to key identifier
Move all the PSA crypto APIs using key handles
to use key identifiers but psa_key_open() and
psa_key_close(). This is done without modifying
any test as key handles and key identifiers are
now the same.

Update the library modules using PSA crypto APIs
to get rid of key handles.

Programs and unit tests are updated to not use
key handles in subsequent commits, not in this
one.

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.

2a99315cc5 Add volatile key identifiers
Volatile key identifiers are introduced in
PSA Crypto API v1.0.0. They are returned by the APIs
when importing or generating or deriving a volatile key.

d2ed4815da Split persistence and key id validation
With key usage based on key identifiers and not
key handles (openless APIs), volatile keys will
also have a key identifier. Thus, isolate key
identifier validation from key persistence
validation to clarify that key identifiers
are not specific to persistent keys.

1c399bdffe Set authmode to optional, if not set
Set authmode to `MBEDTLS_SSL_VERIFY_REQUIRED` when using dtls-srtp,
in case authmode was not set. This is to support self signed certificates
received by the server, which is the case with webRTC. Certificate fingerprints
are verified outside the dtls stack, as defined in RFC 5763.
