[rialto] Add communication protocol library for host and rialto

This cl adds a communication protocol library that includes
Request and Response definitions for communication between the
host and rialto. The Request and Response messages are
(de)serialized in CBOR format and exchanged via vsock, enabling
the handling of partial packets.

In addition, an end-to-end test has been included to cover this
functionality. The test verifies the following steps that
correspond to the intended usage of the library:

- The host sends a Request to rialto serialized in CBOR.
- rialto deserializes the Request, executes it, and prepares a
Response.
- rialto sends the Response to the host serialized in CBOR.
- The host deserializes the Response.

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
