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:
* Add manually written not-supported test cases for the signature
operation when exactly one variant is supported.
* Add manually written positive test cases for the verification
operation when exactly one variant is supported.
* Register that !ECDSA but DETERMINISTIC_ECDSA is not tested yet
(https://github.com/Mbed-TLS/mbedtls/issues/9592).
A commit in the framework will take care of automatically generated test cases.

They're redundant with the automatically generated test cases, but it's
useful to have them when debugging issues with the test code.
