Subject: rust: add abstraction for struct device

Add an (always) reference-counted abstraction for a generic C `struct
device`. This abstraction encapsulates existing `struct device` instances
and manages its reference count.

Subsystems may use this abstraction as a base to abstract subsystem
specific device instances based on a generic `struct device`, such as
`struct pci_dev`.
