Zero-length buffers should be represented in the
psa_crypto_buffer_copy_t struct as NULL if it was created in
psa_crypto_alloc_and_copy(), so reject non-NULL zero-length buffers.

If we have a copy buffer but no original to copy back to, there is not
much sensible we can do. The psa_crypto_buffer_copy_t state is invalid.

Since it is implementation-dependent whether
malloc(0) returns NULL or a pointer, explicitly
represent zero-length buffers as NULL in the
buffer-copy struct, so as to have a uniform
behaviour.

Add function prototypes for psa_crypto_alloc_and_copy() and
psa_crypto_alloc_and_free(), along with the necessary state struct.

If MBEDTLS_BLOCK_CIPHER_NO_DECRYPT, we can't test decrypt for
AES-ECB, so adding this dependency for some test cases

With the introduction of negative option
MBEDTLS_BLOCK_CIPHER_NO_DECRYPT, we don't need to implicitly enable
it through PSA.

tls13 server now does not parse pre-shared key extension unless
there are some psk key exchange modes really available.
For `ephemeral_all/psk_or_ephemeral` configuration pairs, there
wouldn't be any psk key exchange mode available, so the check
of "Pre shared key found" should be inverse.

Automatic testing of our testing is not essential, as our testing
framework may be manually tested. Having automated tests to test our
tests may be left to future work.

Some test cases are using encrypted key file, thus have
dependency on low-level block cipher modules (e.g. AES).
This commit adds unencrypted key file so that we could
get rid of those dependencies.

We need to fully check if the provided session ticket could be
used in the handshake, so that we wouldn't cause handshake
failure in some cases. Here we bring f8e50a9 back.
Example scenario:
A client proposes to a server, that supports only the psk_ephemeral
key exchange mode, two tickets, the first one is allowed only for
pure PSK key exchange mode and the second one is psk_ephemeral only.
We need to select the second tickets instead of the first one whose
ticket_flags forbid psk_ephemeral and thus cause a handshake
failure.
