Generalize the driver discovery and move driver-specific
functionality to the concrete driver implementations.
Currently, this process is tightly coupled to the hsakmt
which is GPU and OS specific.

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.

Update commentary on HWS scheduler support bit for GPU debugging in
the HSA capabilities node properties field.

Extend the current Thunk implementation of queue creation to target
specific SDMA engine IDs.
Also expose the new recommend SDMA engines per IO link from the KFD
sysfs.

When HSA_OVERRIDE_GFX_VERSION is used, save the overrided GFX
version to OverrideEngineId instead of original EngineId. There
are places where real GFX properties still needed, e.g. CWSR size
calculation.

KFD ioctl version is 1.16 on upstream for contiguous memory support.
Remove pc_sampling version, should be added after pc_sample upstream.

New API to support optional alignment parameter for memory allocations.
The alignment should be larger than or equal to page size and a power
of 2.

To differentiate discrete and integrated GPU more flexibly in runtime,
this will aid in querying HSA_AMD_MEMORY_PROPERTY_AGENT_IS_APU
and hipDeviceAttributeIntegrated.

Since PC Sampling not upstream yet, so use 1.16 for
contiguous VRAM allocation, and 1,17 for pc sampling.
