feat(dice): add client API for DICE Protection Environment

RSS provides the DICE Protection Environment
service (DPE). It partially implements the
DPE specification from TCG.

As a DPE profile, it supports the
Open Profile for DICE specification.
https://pigweed.googlesource.com/open-dice/+/refs/heads/main/docs/specification.md

In order to communicate with the service, commands
must be CBOR encoded.
The API implementation:
 - Expose a C API to the upper layer,
 - Do the CBOR encoding, decoding of the DPE
   commands,
 - Rely on the PSA framework to communicate
   with the RSS through an MHU.
