Remove the options marked as deprecated in crypto_config.h:

• PSA_WANT_KEY_TYPE_ECC_KEY_PAIR, PSA_WANT_KEY_TYPE_RSA_KEY_PAIR as well as the corresponding macros MBEDTLS_PSA_{BUILTIN,ACCEL}_KEY_TYPE_{RSA,ECC}_KEY_PAIR
  We can either keep an empty crypto_legacy.h or remove it.
• MBEDTLS_SHA256_USE_A64_CRYPTO_IF_PRESENT, MBEDTLS_SHA256_USE_A64_CRYPTO_ONLY
