Implement flat scratch support for dGPU
...
hsaKmtAllocMemory only allocates aligned address space and sets up
the scratch_physical aperture to match the allocated address space.
Actual allocation of backing memory happens in hsaKmtMapMemoryToGPU.

Fix node 0 system memory allocation for dGPU
...
This is a hack to allow the Runtime to allocate system memory with
PreferredNode=0 on a dGPU system. We allocated it from Node 1
instead so that the node 1 GPU can map the memory. A proper fix
will be implemented together with multi-GPU support.

Setup APE1 on dGPU for coherent access
...
The default is non-coherent access for better performance on dGPU.
Disabled hsaKmtSetMemoryPolicy function on dGPU to prevent app from
overriding the APE1 settings at runtime.
Fixed dGPU VM aperture limit to be inclusive.
