SWDEV-492049 - Remove the handle of Phy Mem from Memobj

The hipGraph will use VMM by default when allocating memory.
However, the handle of Phy mem has been added to Memobj by default.
Since the Memobj will track the whole address range from handle to
handle + size, this needs the system to reserve the whole address
range. If the system range have not reserved by the system, then it
will have the potential issue that clr finds the Memobj incorrectly.

This patch removes the handle from the Memobj to fix this potential
issue.
