Honglei Huang d675a9e3a0 rocr: replace DMABuf export paths by driver interface ...

This change improves code maintainability and error handling by
centralizing DMABuf export functionality in the driver interface.

- Replace direct hsaKmtExportDMABufHandle calls with driver's ExportDMABuf method
- Improve error handling with more specific error status returns
- Add explicit invalid parameter checks and assertions
- Consolidate DMABuf export logic in IPC and VMemory paths
- Propagate detailed error status from driver layer
