Gilles Peskine 8a8aa59f52 PSA interruptible sign/verify: detect unsupported mechanism in start ...

In particular, if interruptible ECDSA is supported but not the deterministic
variant, detect this in psa_sign_hash_start(), whereas before start() would
succeed and psa_sign_hash_complete() would fail. This avoids an
inconsistency between psa_sign_hash() and psa_sign_hash_start() that would
be annoying to handle in test_suite_psa_crypto_op_fail.
