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.

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
