For roc devices create hsa_agent_t handles using a pointer to the
device::Device. This ensures each device has a different hsa_agent_t
handle. This may be necessary to ensure the loader symbol lookup will
search only symbols for the correct device.

- Add assertions to enforce that objects are of the correct kind and
have been allocated.
- Make destructors check if objects have been allocated before
deleting.
- Operations that require a non-NullDevice return failure if given a
NullDevice.
- Use static_cast rather than reinterpret_cast when cohersing from a
base class to a derived class.

Rename functions that access devices to reflect the derived device
they return. This includes the base device::Device and the derived
gpu/pal/roc device classes in both NullDevice and Device forms. Change
to use the least derived versions to clarify what operations will be
available.
