Use the core Driver object in the CPU agent to make it OS/driver
agnostic.
Implement the GetMemoryProperties() and GetCacheProperties methods
for the KFD driver.
[ROCm/ROCR-Runtime commit: a9f6bc8d0e]
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.

Return false if trying to free a NULL pointer (or invalid size)
internally in ROCr. This is to detect errors within ROCr when trying
to free NULL pointers. If a user of ROCr tries to free a NULL
pointer, this condition should be caught at the beginning of the
Runtime::FreeMemory(...) function and return HSA_STATUS_SUCCESS. This
matches the behavior of the free(...) or delete functions that
silently ignores calls when the passed a NULL pointer.

Adds support for AllocateMemoryOnly inside XDNA driver.
Move the IsLocalMemory() check inside the KFD driver
since the XDNA driver can, and needs to, create handles
on system memory buffer objects.
Changed handle variable name from thunk_handle to user_mode_driver_handle,
which is more representative if we support non-GPU drivers.

Adds support for initialzing the XDNA driver so that
a hardware context can be created for an AIE queue.
Right now this initializes the device heap in the driver,
gets the relevant tile parameters for the AIE agent,
and creates a hardware context that backs the AIE queue.

- Use HSA_ALLOCATE_QUEUE_DEV_MEM=1 to create AQL queue in device
memory.
- Before writing AQL packet header to the queue use an SFENCE to ensure
that there is no reodering of the writes over PCIE

Remove KFD-specific Allocate/Free calls from the AMD::MemoryRegion.
The KFD-driver-specific Allocate/Free calls are now implemented in
the KfdDriver. Future changes will migrate the remaining KFD-specific
calls out of AMD::MemoryRegion.
This allows the MemoryRegion to be used across AMD drivers like the
XDNA driver.

[ROCm/ROCR-Runtime commit: 68669f4e1a]
Adds the initial KFD driver interface and use it to open the
KFD from amd_topology.cpp.
This change is to show the direction of the Driver interface for
initially supporting the KFD and to get feedback on the approach.
For now we wrap relevant ROCt calls behind this generic driver
interface so that we can generalize core ROCr components like
MemoryRegion, Runtime, etc.
Now that ROCt is incorporated into ROCr, we can more fully integrate
ROCt into the Driver interface. Ideally, we get to a point where
the generic Driver interface can support KFD, XDNA, and potential
future drivers.

[ROCm/ROCR-Runtime commit: c42ff44a6a]
Add a new driver interface as a core ROCr component.
The driver component provides an interface for ROCr to interact with
agent kernel-model drivers in a generic way. This interface will be used
to interact with the XDNA NPU driver. Eventually, the ROCt library's
functionality should be implemented behind this interface.
For now the interface provides basic queue and memory allocation
for supporting HSA queues and signals and matches the thunk API
closely.
