* libhsakmt/virtio: change shmem size to 80
Some DGPU props have a lot of information,
so it is necessary to increase the size of shmem.

* libhsakmt/virtio: use BO handle instead of pointer in memory registration
Change vhsakmt_map_to_gpu() return type from void* to vhsakmt_bo_handle
to properly handle buffer object information. This allows access to
both the host address and resource ID needed for memory registration.

* libhsakmt/virtio: Improve memory mapping logic
- Update vhsakmt_mappable() to check NoAddress flag and require HostAccess
- Remove mappable checks in cpu_map/unmap to allow all BOs to be mapped
- Set BO flags properly in vhsakmt_alloc_memory and scratch memory creation
- Ensure scratch memory is correctly flagged for proper handling

* libhsakmt/virtio: add no svm mode for libhsakmt virtio
Add no svm mode for libhsakmt virtio driver, in no svm mode userptrs
need UMD to manage, so add interval tree to manage them.
New Features:
- Add augmented red-black tree based interval tree implementation
* Implement RB-tree insertion, deletion, and color balancing
* Provide interval query for fast overlapping range lookup
* Based on Linux kernel's augmented rbtree implementation
- Improve userptr memory management
* Use interval tree to efficiently track userptr memory regions
* Support finding registered memory within given address ranges
* Optimize memory mapping and unmapping performance

This patch adds VirtIO support to the libhsakmt library, enabling communication
with AMD GPUs via VirtIO.
Details
- CMakeLists.txt: Added a new CMakeLists.txt file for the VirtIO component
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.
