695c4cb7ea If a cipher algorithm is not supported, fail during setup
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.

0c3a071300 Make psa_key_derivation_setup return early if the key agreement is not supported
Otherwise the systematically generated algorithm-not-supported tests
complain when they try to start an operation and succeed.
