[quant][improvement][better-engineering] Refactored get_supported_device_types into common_quantization.py (#79607)
Summary:
Both test_quantized_tensor.py and test_quantize_fx.py had the same
get_supported_device_types function defined. This PR refactors it into
the common_quantization.py file for common usage
Test Plan:
```
python test/test_quantization.py
```
