[PATCH v5 0/1] MR10561: secur32: Fix handling by SChannel for CNG/NCrypt client certificates for mTLS

[Benoît Legat (＠blegat)]

Part 3 of my attempt to run the [Niko Home Control programming software](https://appdb.winehq.org/objectManager.php?sClass=application&iId=21635) under Wine.

If I understand correctly, the current implementation only supports retrieving via the legacy CryptoAPI (CAPI). The Niko app uses Cryptography Next Generation (CNG/NCrypt) so this PRs adds support for it in acquire_credentials_handle.
