✨[Feature] Automatically remove output repacking for `convert_method_to_trt_engine` calls

[gs-olive]

Context

For fully-supported models having multiple output Tensors, Torch often appends a Tuple/List packing function call to the scripted IR. This can cause convert_method_to_trt_engine, which would otherwise succeed due to converter coverage, to fail.

Details

This proposed feature would automatically detect and remove unnecessary output packing schemes, such as prim::TupleConstruct and prim::ListConstruct, which are applied to the outputs of existing TRT engines, thereby allowing more models to be fully converted to their TRT engine counterparts directly.
