Opaque RSA keys introduced in #5625 and extended in #5711 can only do signatures, with mbedtls_pk_sign[_ext](). This task is to extend them to also support decryption (PKCS#1v1.5, not OAEP) with mbedtls_pk_decrypt().

  • Implement pk_opaque_decrypt() in pk_wrap.c and register it in mbedtls_pk_rsa_opaque_info.
  • Make sure it's tested, either by extending and existing test function or writing a new one, as is more convenient. Testing can be done using known values as decryption is deterministic.

Depends on: #5761
