lib: add blobgen framework
This adds a framework for en/decrypting data blobs. Some SoCs have support for hardware crypto engines that can en/decrypt using keys that a tied to the SoC and are visible for the crypto hardware only. With this patch it's possible to encrypt confidential data using these keys and to decrypt it later for usage.
