1) Separate out local communication from remote communication
2) Directly pass root/leafdata to MPI when suitable

Update pack/unpack routines to do packing/unpacking for all neighbors in at most two routines
One is used to pack data in self to self communication; The second is used for remote communication.
So
Update pack/unpack routines to do packing/unpacking for all neighbors in at most two routines
One is used to pack data in self to self communication; The second is used for remote communication.
So that on GPU, we can use at most two kernels to do packing/packing for all neighbors instead of multiple kernels
