[core] Simplify self types in device::resource.

Change various functions that have no need to create an owning
reference to the `Device` to accept `&self` instead of `&Arc<Self>`.

Change `ParentDevice::same_device` to accept `&Device` as the point of
comparison, not `&Arc<Device>`. Call sites will use Deref conversion,
so no callers need to be changed.
