Related-To: LOCI-4172, LOCI-4305, LOCI-4306 - Create a new IPC Memory handle upon call to getIpcMemHandle if the previous handle has been freed. - Release the Ipc Memory Handle when zeMemPutIpcHandle is called. - Create a new IPC Handle for tracking thru zeMemGetAllocProperties when ze_external_memory_export_fd_t is used. - Convert FD to opaque IPC handle and IPC Handle to FD.
