[opentitantool] Add support for HyperDebug

Add a Transport implementation for the HyperDebug board.  The
implementation uses the rusb (Rust libusb) for finding the HyperDebug
USB device, and for bulk communication to do e.g. SPI communication.
Additionally, the impementation open the Linux /dev/ttyUSBn files
using a Rust serialport crate, which is used for serial communication
with the OPenTitan chip, as well as for sending generic text commands
to HyperDebug itself, to do e.g. GPIO-related operations.

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.

About this repository

This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.

Documentation

The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
