samples: add first Rust examples The beginning of a set of Rust modules that showcase how Rust modules look like and how to use the abstracted kernel features. It also includes an example of a Rust host program with several modules. These samples also double as tests in the CI.

samples: rust: add Rust PCI sample driver This commit adds a sample Rust PCI driver for QEMU's "pci-testdev" device. To enable this device QEMU has to be called with `-device pci-testdev`. The same driver shows how to use the PCI device / driver abstractions, as well as how to request and map PCI BARs, including a short sequence of MMIO operations.

rust/kernel: Add faux device bindings This introduces a module for working with faux devices in rust, along with adding sample code to show how the API is used. Unlike other types of devices, we don't provide any hooks for device probe/removal - since these are optional for the faux API and are unnecessary in rust.
