* libhsakmt: Update hsakmt_fmm_get_handle to support address range
Currently, hsakmt_fmm_get_handle works only if the address is allocated
(staring) value. Update it so it can find the handle if address falls in
the valid allocated range. This is useful for AMD infinity storage
feature where data needs to be transferred to any memory within in the
allocated range

* libhsakmt: Introduce AMD Infinity Storage (AIS) API
Add hsaKmtAisReadWriteFile() API to support AMD Infinity Storage. The
API moves data directly from GPU VRAM to a file.
v2: Add in/out ioctl arguments to provide more status information to
user space. Modify hsaKmt API also accordingly.

* rocr: Initial implementation of AMD Infinity Storage (AIS)
Implement first two API: hsa_amd_ais_file_write and hsa_amd_ais_file_read
v2: Change API from hsa_amd_ to hsa_amd_ais_
Change API to take in handle instead of fd for compatibility accross
different platforms

This patch uses udmabuf driver to allocate system memory instead of using amdgpu
driver for APU. With this function app can account its consumed system memory by
cgroup mechanism. This function is enabled by env variable HSA_USE_UDMABUF.

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.

[ROCm/ROCR-Runtime commit: 1a4adaf7bc]
Currently registering graphics memory without specifying a target
node will return a memory handle that's not a virtual address.
As a result, ROCr is forced to register with a target node for
IPC usage.
Mapping memory without specifying a target node afterwards will
result in mapping to the target node that was imported because the
previous import call flags this node targeting action to future mapping.
For ROCr IPC usage, ROCr wants to map to all GPU nodes if the target node
is not specified.
Allow the caller to register graphics handles that returns a virtual
address without having to specify the target node so that the caller
can make a subsequent map call to all GPUs.
