Add a new driver interface as a core ROCr component.
The driver component provides an interface for ROCr to interact with
agent kernel-model drivers in a generic way. This interface will be used
to interact with the XDNA NPU driver. Eventually, the ROCt library's
functionality should be implemented behind this interface.
For now the interface provides basic queue and memory allocation
for supporting HSA queues and signals and matches the thunk API
closely.
