Add a new BoundInternal device context type for cases where bus
abstractions need access to internal device infrastructure, where
CoreInternal would not be justified.
Introduce the InternalBoundContext marker trait, implemented by both
CoreInternal and BoundInternal, to allow methods that require internal
bus abstraction access to a bound device to be generic over both
contexts.
The deref hierarchy now has two branches:
- CoreInternal<'a> => Core<'a> => Bound => Normal
- BoundInternal => Bound => Normal
Update impl_device_context_deref! and impl_device_context_into_aref!
macros to emit the BoundInternal => Bound deref and the corresponding
ARef conversion.
