Bugfix
* Fix TLS 1.3 handshakes using opaque pre-shared keys configured through
mbedtls_ssl_conf_psk_opaque(). The client computed an incorrect PSK
binder, the server rejected the PSK identity, and the early key
schedule exported the key with psa_export_key(), which fails for
non-exportable keys. Opaque PSKs are now consumed directly via
psa_key_derivation_input_key(). Fixes #10956.
