When OPENTHREAD_CONFIG_CRYPTO_PLATFORM_CCM_ONE_SHOT_ENABLE is set,
AesCcm::Engine::ProcessOneShot() calls the new weak platform hook:
otPlatCryptoAesCcmProcessOneShot()
The hook operates in-place on a contiguous [payload|tag] buffer,
mapping to a one-shot PSA AEAD call or a packet-oriented hardware engine.
Default weak implementations:
- PSA path: psa_aead_encrypt / psa_aead_decrypt (one-shot).
- mbedTLS path: mbedtls_ccm_encrypt_and_tag / mbedtls_ccm_auth_decrypt,
both support in-place (input == output).
