Fix torch.accelerator api abort when passing invaild device (#143550)

Browse Source 
# Motivation
Fix https://github.com/pytorch/pytorch/issues/143543

# Solution
We should raise python exception instead of aborting...

# Additional Context
without this PR:
```python
>>> import torch
>>> torch.accelerator.current_stream(torch.accelerator.device_count())
terminate called after throwing an instance of 'c10::Error'
  what():  device is out of range, device is 2, total number of device is 2.
