624fc2e0de Move TLS 1.3 verify-result setting for PSK 
When we are doing PSK, we'd like to set verify_result to
MBEDTLS_X509_BADCERT_SKIP_VERIFY. Previously this was done in
mbedtls_ssl_set_hs_psk() but this is inadequate since this function may
be called for early data (where certificate verification happens later
in the handshake.

Instead, set this value after writing / processing the encrypted
extensions on the server / client respectively, so that we know whether
we are doing certificate verification or not for sure. This change is
effective only for TLS 1.3 as TLS 1.2 sets verify_result for PSK in
ssl_parse_certificate_coordinate().

7b2d72aaf0 ssl: replace PSA_ALG_ECDSA with MBEDTLS_PK_ALG_ECDSA 
When the key is parsed from PK it is assigned the pseudo-alg
MBEDTLS_PK_ALG_ECDSA. Trying to run "mbedtls_pk_can_do_psa" with an hardcoded
deterministc/randomized ECDSA can make the function to fail if the proper
variant is not the one also used by PK.
This commit fixes this problem.

1038b22d74 Reduce the level of logging used in tests 
This should avoid running into a bug with printf format specifiers one
windows.

It's also a logical move for actual tests: I used the highest debug
level for discovery, but we don't need that all the time.
