Fix config for MBEDTLS_SSL_PROTO_TLS1_3
Fix config for MBEDTLS_SSL_PROTO_TLS1_3

Remove MBEDTLS_HKDF_C as it is not needed since #5838

Reasoning: we need SHA-256 or SHA-384 via PSA because they're used by HKDF which is now always done via PSA. If in addition to that USE_PSA is enabled, then everything is done via PSA so that's enough. Otherwise, we need the software implementation of SHA-256 or SHA-384, plus MD_C because we're using a VIA_MD_OR_PSA_BASED_ON_USE_PSA as discussed above.
