[UR] Change IPC handle get function to return the original pointer (#20490)
This commit makes the UR interfaces implementing urIPCGetMemHandleExp
return the exact memory pointer from UMF instead of copying the handle
data. This is done as the exact pointer is expected to be passed when
calling umfPutIPCHandle in the urIPCPutMemHandleExp interface.
