Unifies OpInfo dtype tests (#60157)
Summary:
Simplifies the OpInfo dtype tests and produces nicer error messages, like:
```
AssertionError: Items in the first set but not the second:
torch.bfloat16
Items in the second set but not the first:
torch.int64 : Attempted to compare [set] types: Expected: {torch.float64, torch.float32, torch.float16, torch.bfloat16}; Actual: {torch.float64, torch.float32, torch.float16, torch.int64}.
The supported dtypes for logcumsumexp on cuda according to its OpInfo are
{torch.float64, torch.float32, torch.float16, torch.int64}, but the detected supported dtypes are {torch.float64, torch.float32, torch.float16, torch.bfloat16}.
The following dtypes should be added to the OpInfo: {torch.bfloat16}. The following dtypes should be removed from the OpInfo: {torch.int64}.
```
