Fix build with mbedtls v3.6 PSA but without TLS 1.3 or session tickets

[misch7]

Problems

1. Build fails when support for session tickets is disabled (thus HAS_SESSION_TICKETS undefined in lib/vtls/mbedtls.c).
2. Runtime error for all TLS connections when built with MBEDTLS_USE_PSA_CRYPTO but without TLS 1.3 support:

$ ./build/bin/curl --insecure --verbose --head https://curl.se
* ssl_handshake returned: (-0x3E80) PK - Bad input parameters to function
curl: (35) ssl_handshake returned: (-0x3E80) PK - Bad input parameters to function

Solutions

1. mbedtls_ssl_conf_tls13_enable_signal_new_session_tickets requires the conditionals that are already covered by HAS_SESSION_TICKETS, see include/mbedtls/ssl.h (and the lines above).
   MBEDTLS_SSL_TLS1_3_SIGNAL_NEW_SESSION_TICKETS_ENABLED always resolves to 1 because it is only meant as a boolean parameter for the function.

2. When Mbed TLS is built with PSA, it must always be initialized regardless of the TLS 1.3 support.

Ah, can you just rebase this again and force-push? I believe my symbol fix in the mean time made it conflict a little.

Done and also fancier now with less commits. ^^
