ECDSA has two variants: deterministic (PSA_ALG_DETERMINISTIC_ECDSA) and randomized (PSA_ALG_ECDSA). The two variants are different for signature but identical for verification. Mbed TLS accepts either variant as the algorithm parameter for verification even when only the other variant is supported, so we need to handle this as a special case when generating not-supported test cases. In this commit, suppress generated test cases for operation failures due to unsupported ECDSA when exactly one of the two ECDSA variants is supported. This edge case will only be tested manually (done in mbedtls or TF-PSA-Crypto in the commit "Fix edge case with half-supported ECDSA (manual test cases)"). Changes to the generated output: in `test_suite_psa_crypto_op_fail.generated.data`, wherever one of `!PSA_WANT_ALG_DETERMINISTIC_ECDSA` or `!PSA_WANT_ALG_ECDSA` appears as a dependency, add the other one.
