Generally, code review is enough to ensure that PSA APIs are indeed used where
they should be when `MBEDTLS_USE_PSA_CRYPTO` is enabled.

For some APIs, for example with `mbedtls_ssl_conf_psk_opaque()`, unit testing
does not make sense, so we only have integration testing.
For some APIs, for example with `mbedtls_ssl_conf_psk_opaque()`, testing in
`test_suite_ssl` was historicaly not possible, so we only have testing in
`ssl-opt.sh`.

Changes in this category rarely require specific testing, as everything should
be already be covered by running the existing tests in a build with

`MBEDTLS_USE_PSA_CRYPTO` enabled; however we need to make sure the existing
test have sufficient coveraged, and improve them if necessary.
However, if additional logic is involved, or there are run-time decisions about
whether to use the PSA or legacy code paths, specific tests might be in order.
