rust: implement `IdArray`, `IdTable` and `RawDeviceId`
Most subsystems use some kind of ID to match devices and drivers. Hence,
we have to provide Rust drivers an abstraction to register an ID table
for the driver to match.
Generally, those IDs are subsystem specific and hence need to be
implemented by the corresponding subsystem. However, the `IdArray`,
`IdTable` and `RawDeviceId` types provide a generalized implementation
that makes the life of subsystems easier to do so.
