HYPRE: add option -hypre_umpire_device_pool_size <size in MiB>

When hypre is configured with Umpire (recommended by hypre), the default Umpire pool size on device is set
to 4 GB per process by hypre

HYPRE: add option -hypre_umpire_device_pool_size <size in MiB>

When hypre is configured with Umpire (recommended by hypre), the default Umpire pool size on device is set
to 4 GB per process by hypre which could lead to out-of-memory when one maps multiple MPI processes to one GPU.
