[ROCm/ROCR-Runtime commit: 5285c24657]
Modify agent initialization to support different driver types,
to enable KFD_VIRTIO dirver for CPU and GPU agent here.
1. Add driver_type parameter to CpuAgent and GpuAgent constructors
2. Update topology discovery to handle multiple driver types
3. Fix MakeMemoryResident return value check in VirtioDriver
4. Add helper function IsGPUDriver to check driver types
5. Update agent discovery to iterate through all available drivers
This change makes the runtime more flexible by removing hardcoded KFD
driver assumptions and properly handling different driver backends.

This commit adds virtio driver support to the ROCm runtime by:
1. Implementing KfdVirtioDriver class that inherits from core::Driver
2. Adding KFD_VIRTIO to DriverType enum
3. Registering virtio driver discovery function in topology
4. Adding virtio driver source files to CMake build
The virtio driver implementation provides basic memory management and
queue operations for virtualized GPU environments. Some advanced features
like PC sampling and SMI are currently not supported.
Key changes:
- Add new files: amd_kfd_virtio_driver.h/cpp
- Update CMakeLists.txt to include virtio driver
- Add VIRTIO to DriverType enum in driver.h
- Register virtio driver in amd_topology.cpp

of libhsakmt.
- hsakmt_virtio.c/h: Implemented the core VirtIO functionality, including
VirtIO GPU device initialization, command execution, and memory management.
- virtio_gpu.c/h: Contains the implementation of the VirtIO GPU device,
including ioctl handling, shared memory management, and command execution.
- hsakmt_virtio_events.c: Implements event handling for VirtIO, such as event
creation, destruction, setting, resetting, and querying event states.
- hsakmt_virtio_memory.c: Manages memory operations for VirtIO, including memory
allocation, freeing, mapping, and unmapping.
- hsakmt_virtio_queues.c: Implements queue management for VirtIO, including
queue creation, destruction, and updating.
- hsakmt_virtio_topology.c: Handles system and node properties for VirtIO.
- hsakmt_virtio_vm.c: Manages VM-related operations for VirtIO, such as
reserving and dereserving VA space.
- include/linux/virtgpu_drm.h: Contains DRM definitions for VirtIO GPU.
Key Features
- VirtIO GPU Initialization: The library can now initialize a VirtIO GPU device
and communicate with it.
- Command Execution: Supports executing commands on the VirtIO GPU device.
- Memory Management: Provides functions for allocating, freeing, mapping, and
unmapping memory for VirtIO operations.
- Event Handling: Implements a comprehensive event system for VirtIO.
- Queue Management: Allows for creating, destroying, and updating queues
on the VirtIO GPU device.
- System and Node Properties: Retrieves and manages system and node
properties for VirtIO.

Add AllocateScratchMemory interface to Driver base class and implement it
in both KFD and XDNA drivers. This change encapsulates the low-level
scratch memory allocation details within driver implementations, making
the code more maintainable and the interface cleaner.

- Implement the interface in KfdDriver with existing allocation logic
- Add stub implementation in XdnaDriver
- Update GpuAgent to use the new interface instead of direct KMT calls
