Add two pointer attributes APIs:
hsaKmtQueryPointerInfo - allow the user to query the memory information
using a pointer. This pointer can point to any address inside the
range known to HSA.
hsaKmtSetMemoryUserData - allow the user to attach data to a pointer to
add memory tracking information. This pointer must match the start
address of a memory allocation or registration.
TODO: This patch implements support on dGPU. Needs to add APU.

Fix hsaKmtRegisterMemory to be a no-op for now and move the multi-GPU
implementation to hsaKmtRegisterMemoryToNodes. Make GPU memory mappings
of host memory visible to all GPUs by default. Device memory is still
visible to the allocating GPU only by default (but can be overridden
with hsaKmtRegisterMemoryToNodes for experimenting with P2P).
