🐛 Check for the casting of the unary operations in conversion/impl/unary/ops.py

The following lines-
```
    if (isinstance(input_val, TRTTensor)) and (
        input_val.dtype == trt.int8 or input_val.dtype == trt.int32
    ):
        input_val = cast_trt_tensor(ctx, input_val, trt.float32, name)
```
are present in almost all the unary ops. Check its requirement
