Added more version comparison operations (#63848)

Added more version comparison operations (#63848)

Summary:
Currently the [TorchVersion](https://github.com/pytorch/pytorch/blob/1022443168b5fad55bbd03d087abf574c9d2e9df/torch/torch_version.py#L13) only only supports 'greater than', and 'equal to' operations for comparing torch versions and something like `TorchVersion('1.5.0') < (1,5,1)` or `TorchVersion('1.5.0') >= (1,5)` will throw an error.

I have added 'less than' (`__lt__()`), 'greater than or equal to' (`__ge__()`) and 'less than or equal to' (`__le__()`) operations, so that the TorchVersion object can be useful for wider range of version comparisons.
