Implement OpenReg device autoload mechanism

This PR aims to apply device autoload mechanism to the OpenReg module with some simple changes.

Change

Before

import torch
import torch_openreg

x = torch.tensor([1, 2, 3], device="openreg")
print(x)

After

import torch

# No need to import torch_openreg manually!
x = torch.tensor([1, 2, 3], device="openreg")
print(x)
