[roll] Roll fuchsia [cqhci] Add transfer manager

TransferManager is responsible for managing the state of the Task
Descriptor List and submitting tasks to the CQE.

Transfer and DirectCmd are RAII types which represent an in-flight task.
They automatically release their resources when dropped, which is
usually done after an interrupt has been received notifying the driver
of a task completion.

TransferManager::prepare_transfer will block until a slot is available
in the TDL (and similarly for prepare_dcmd and the single DCMD slot).
