This is not a HAL change. It just adds a command to msg_formatting.h as
a service to vendors who have to augment the protocol between the HAL
service and the TA or other implementation with janitorial commands that
don't effect the HAL interface.

These changes accumulated during the integration with the Pixel specific
impelemtation. The make it easiser to integrate an GUI renderer with the
core logic.

This reference implementation implements the core
logic of the confirmation provider including the
cryptographic operations. For a full implementation
a user interface and a few policy checks are missing.

Includes:
A light weight CBOR generator
This patch adds a header only CBOR generator and unit tests.
It allows expressing CBOR datastructures in C++ for subsequent
serialization. The implementation performs no memory allocation
and only depends on stdint.h (for (u)intx_t) and stddefs.h (for size_t).
It is tailored for use in constrained environments such as TEEs.
Convenience method for generating a SHA256 HMAC

HAL definition for high assurance confirmation providers.
High assurance confirmation providers allow relying parties
to prompt the user for confirming a short piece of information.
If the user confirms, the result is a signed message indicating
that the user has seen the message. For a high assurance confirmation
provider this must also be true if Android and the Linux kernel
are compromised.
