For GFX 9.4.3, interrupt handling needs to be updated for:
- Interrupt cookie will have a NodeId field. Each KFD
  node needs to check the NodeId before processing the
  interrupt.
- For CPX mode, there are additional checks of client ID
  needed to process the interrupt.
- Add NodeId to the process drain interrupt.
