🐛 [Bug] Remove prepare_inputs and passing inputs during compilation.

[peri044]

Bug Description

Currently, we pass trt_arg_inputs and trt_kwarg_inputs to compile_module https://github.com/pytorch/TensorRT/blob/main/py/torch_tensorrt/dynamo/_compiler.py#L682. These are actually not being used. The prepare inputs call also fails sometimes during graph parsing for dry run. Since we read all the input info from graph metadata now, we can consider removing user inputs being passed around internally.
