  [flang][cuda] Update device descriptor on data transfer (#114838)

When the destination of the data transfer is a global we might need to
sync the descriptor after the data transfer is done. This is the case
when the data transfer is from host/device to device as reallocation
might have happened and the descriptor on the device needs to take the
new values written on the host.

A new entry point is added `CUFDataTransferGlobalDescDesc` with the sync
when needed.
