rust: samples: add tracepoint to Rust sample This updates the Rust printing sample to invoke a tracepoint. This ensures that we have a user in-tree from the get-go even though the patch is being merged before its real user.

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.
