It doesn't make sense for psa_mac_verify() to return
PSA_ERROR_BUFFER_TOO_SMALL since it doesn't have an output buffer. But this
was happening when requesting the verification of an unsupported algorithm
whose output size is larger than the maximum supported MAC size, e.g.
HMAC-SHA-512 when building with only SHA-256 support. Arrange to return
PSA_ERROR_NOT_SUPPORTED instead.

In some cases, a cipher operation for an unsupported algorithm could succeed
in psa_cipher_{encrypt,decrypt}_setup() and fail only when input is actually
fed. This is not a major bug, but it has several minor downsides: fail-late
is harder to diagnose for users than fail-early; some code size can be
gained; tests that expect failure for not-supported parameters would have to
be accommodated to also accept success.
This commit at least partially addresses the issue. The only completeness
goal in this commit is to pass our full CI, which discovered that disabling
only PSA_WANT_ALG_STREAM_CIPHER or PSA_WANT_ALG_ECB_NO_PADDING (but keeping
the relevant key type) allowed cipher setup to succeed, which caused
failures in test_suite_psa_crypto_op_fail.generated in
component_test_psa_crypto_config_accel_xxx.
Changes in this commit:
* mbedtls_cipher_info_from_psa() now returns NULL for unsupported cipher
algorithms. (No change related to key types.)
* Some code that is only relevant for ECB is no longer built if
PSA_WANT_ALG_ECB_NO_PADDING is disabled.

Otherwise the systematically generated algorithm-not-supported tests
complain when they try to start an operation and succeed.

MBEDTLS_HAVE_TIME is documented as: "System has time.h and time()."
If that is not defined, do not attempt to include time.h.
A particular problem is platform-time.h, which should only be included if
MBEDTLS_HAVE_TIME is defined, which makes everything messier. Maybe it
should be refactored to have the check inside the header.

Extend mbedtls_ssl_set_hs_own_cert() to reset handshake cert list
if cert provided is null. Previously, mbedtls_ssl_set_hs_own_cert()
only provided a way to append to the handshake certificate list,
without providing a way to replace the handshake certificate list.

The Mbed TLS coding standard specifies that "check" functions must return 0
for success (i.e. feature present), while "has" functions should return 1 for
true. Since we were using "check" to do the actual check, and "has" to get the
cached value, having inverted values here would be confusing. Therefore,
rename "check" to "determine", as that's what those functions are doing.

Sign rsa is not thread safe. Remove it from current code.
And a thread-safe version should be re-introduce in future.
