rocr/driver: add GetDeviceHandle to driver interface

This commit introduces a new GetDeviceHandle API to the driver
interface, allowing retrieval of the device handle for a
specific node.

- Implemented GetDeviceHandle in KfdDriver to fetch the AMD GPU
  device handle using hsaKmtGetAMDGPUDeviceHandle.
- Added a stub implementation of GetDeviceHandle in XdnaDriver
  that returns HSA_STATUS_ERROR.
- Modified GpuAgent::InitLibDrm to use driver().GetDeviceHandle
  instead of directly calling hsaKmtGetAMDGPUDeviceHandle.
