The HSM used in provisioning infrastructure uses a custom mechanism identifier (CKM_AES_KW = (CKM_VENDOR_DEFINED + 0x170)) even though the implementation follows the RFC 3394 specification. The CKM_AES_KW implemented by Thales is also equivalent to the KW algorithm specified by NIST SP 800-38F. This change adds a custom Wrap::VendorThalesAesKw mechanism to hsmtool to be able to wrap/unwrap private keys with AES_KW. This is similar to lowRISC#26565.
