Dayatsin/develop vmm pointer info (#305)

* rocr: hsa_amd_pointer_info to support VMEM pointers

Extend hsa_amd_pointer_info to support virtual memory addresses.

If hsa_amd_pointer_info is called on an address that is reserved but not
mapped to memory, then the pointer type will be reported as
HSA_EXT_POINTER_TYPE_RESERVED_ADDR.

If hsa_amd_pointer_info is called on an address that is mapped, then the
pointer type will be reported as HSA_EXT_POINTER_TYPE_HSA_VMEM

* rocrtst: VirtMemory_Basic_Test test for pointer info

Extend rocrtstFunc.VirtMemory_Basic_Test to test for
hsa_amd_pointer_info

* rocrtst: Add SVM Memory Test
