Add pointer attributes API

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.
